Secondary Mathematics I
Strand: FUNCTIONS - Interpreting Linear and Exponential Functions (F.IF)
Understand the concept of a linear or exponential function and use function notation. Recognize arithmetic and geometric sequences as examples of linear and exponential functions (Standards F.IF.1-3)
. Interpret linear or exponential functions that arise in applications in terms of a context (Standards F.IF.4-6)
. Analyze linear or exponential functions using different representations (Standards F.IF.7, 9)
Graph functions expressed symbolically and show key features of the graph, by hand in simple cases and using technology for more complicated cases.★
This task could be used as a review problem or as an assessment problem after many different types of functions have been discussed. Since the different parameters of the functions are not given explicitly, the focus is not just on graphing specific functions but rather students have to focus on how values of parameters are reflected in a graph.
Bank Account Balance
The purpose of this task is to study an example of a function which varies discretely over time.
Students may use the applet in this lesson to graph a function and a tangent line and view its equation.
The purpose of this task is twofold: first using technology to study the behavior of some exponential and logarithmic graphs and secondly to manipulate some explicit logarithmic and exponential expressions.
The applet on this site allows the students to manipulate the graph of a function by changing the value of exponents, coefficients and constants.
FUNCTIONS - Interpreting Linear and Exponential Functions (F.IF) - Sec Math I Core Guide
The Utah State Board of Education (USBE) and educators around the state of Utah developed these guides for the Secondary Mathematics I Interpreting Linear and Exponential Functions (F.IF).

Graphing Rational Functions
This task starts with an exploration of the graphs of two functions whose expressions look very similar but whose graphs behave completely differently.
With this interactive applet students are able to create graphs of functions and sets of ordered pairs on the same coordinate plane.
Graphs of Power Functions
This task requires students to recognize the graphs of different (positive) powers of x.
Graphs of Quadratic Functions
This exploration can be done in class near the beginning of a unit on graphing parabolas. Students need to be familiar with intercepts, and need to know what the vertex is. It is effective after students have graphed parabolas in vertex form, but have not yet explored graphing other forms.
Identifying Exponential Functions
The task is an introduction to the graphing of exponential functions.
Identifying graphs of functions
The goal of this task is to get students to focus on the shape of the graph of an equation and how this changes depending on the sign of the exponent and on whether the exponential is in the numerator or denominator.
Introduction to the Materials (Math 1)
Introduction to the Materials in the Mathematics One of the The MVP classroom experience begins by confronting students with an engaging task and then invites them to grapple with solving it. As students ideas emerge, take form, and are shared, the teacher orchestrates the student discussions and explorations towards a focused mathematical goal. As conjectures are made and explored, they evolve into mathematical concepts that the community of learners begins to embrace as effective strategies for analyzing and solving problems.
The applet in this lesson allows students to manipulate variables and see the changes in the graphed line.
Modeling London's Population
The purpose of this task is to model the population data for London with a variety of different functions. In addition to the linear, quadratic, and exponential models, this task introduces an additional model, namely the logistic model.
Module 2: Linear & Exponential Functions - Student Edition (Math 1)
The Mathematics Vision Project, Secondary Math One Module 2, Linear and Exponential Functions, begins with a learning cycle that introduces contexts with continuous domains and defining linear functions as having a constant rate of change and exponential functions as having a constant ratio over equal intervals.
Module 2: Linear & Exponential Functions - Teacher Notes (Math 1)
Mathematics Vision Project, Secondary Math One Module 2 Teacher Notes, Linear and Exponential Functions, begins with a learning cycle that introduces contexts with continuous domains and defining linear functions as having a constant rate of change and exponential functions as having a constant ratio over equal intervals.
Module 3: Features of Functions - Student Edition (Math 1)
The Mathematics Vision Project, Secondary Math One Module 3, Features of Functions, is the culminating functions module in Secondary Math I. In this module, students broaden their thinking about functions to relationships that are not either linear or exponential.

More Complicated Functions: Introduction to Linear Functions
This lesson is designed to reinforce the concept of linear functions and ask students to write functions using English, tables and algebra.
Multi-Function Data Flyer
The applet in this lesson allows students to plot ordered pairs and then change the values in order to observe the effects of those changes.
This collection of resources to teach graphing equations in slope intercept form includes warm-up exercises, a video presentation explaining the topic, practice exercises, worked examples, practice problems, and a review.
Through this lesson students will understand how to graph functions.
This lesson unit is intended to help educators assess how well students are able to translate between graphs and algebraic representations of polynomials.
This task provides an application of polynomials in computing. This purpose of this task is to serve as an introduction, and motivation, for the study of end behavior of polynomials, content specifically addresses in standard F-IF.C7c.
Student Task: Sorting Functions
Students are given four graphs, four equations, four tables, and four rules.
Their task is to match each graph with an equation, a table and a rule.
