During this instructional activity, students will be introduced to interpreting functions. A function is a relationship between two sets: the domain (input values) and the range (output values).

In this task involving temperature conversions, students construct a linear function given two input-output pairs, investigate the inverse of a linear function, and reason about quantities and/or solving a linear equation. Aligns with...

Find features of exponential functions of the basic form f(x)=a*r^x given their formula. Features in question are the initial value, the common ratio, and output-values that correspond to various input-values. Students receive immediate...

[Free Registration/Login may be required to access all resource tools.] Students will understand functions by writing expressions for input-output tables. Students watch videos, examine guided notes, review vocabulary and attempt...

[Free Registration/Login may be required to access all resource tools.] Evaluate a function rule by finding outputs for a given input

In general this tutorial tries to explain the reasons for things, and help you understand what's going on inside the system. The idea is to empower you to solve new problems and get the most out of your computer. Thus there's plenty of...

The interactive activity has students explore simple linear functions by looking for patterns in the outputs to determine the function. The activity and teacher resources are included.

The interactive activity has students explore simple linear functions involving whole numbers by looking for patterns in the outputs to determine the function. The activity and teacher resources are included.

This task asks students to analyze a set of data about the height of a basketball for each time it bounces. They choose a model that reasonably fits the data and use the model to answer questions about the physical context. This second...

The driver/BIOS functions are closely associated with the operating system and this site clearly explains how they work together.

An interactive "machine" allows you to see first hand how a function works. Enter several input values, receive the output values, and determine the algebraic function.

Article from Benbest entitled "Chapter 6 -- Basic Cerebral Cortex Function Other than Vision."

During this lesson, eighth grade students will interpret the perimeter of a train of triangles, squares, trapezoids, or hexagons as a function (for each input, there will be exactly one output). Students will represent their data in a...

This site is a tutorial for students in algebra 2 or for those who need a refresher. The site has explanations, definitions, examples, practice problems and practice tests are found covering topics such as linear equations, graphing,...

Eighth graders work with input values (the year) and output values (the amount of garbage that year) in a table about the garbage produced in the US. They study the table to answer specific questions, state whether it represents a linear...

Given the formula of an arithmetic sequence, either in explicit form or in recursive form, find a specific term in the sequence. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or...

For this task, students examine data on the elevation and the minutes into a ride for a tram that is traveling up a mountain and write an equation for the function that models the relationship between the two variables. Aligns with...

A transformation is a function that takes points in the plane as inputs and gives other points as outputs. You can think of a transformation as a rule that tells you how to create new points from old points.

Practice finding the equation of a line passing through two points. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Write equations in point-slope form given two pairs of values, and convert the equation into slope-intercept form. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

The Number Cruncher, provided by Shodor Education Foundation, is an activity on linear functions. "This activity allows the user to enter numbers and then attempt to find the rule the activity is using to get the data in the output box."

The purpose of this task is to introduce students to an exponential decay function in the form f(x) = abx, with a concrete interpretation of the decay factor b. A table shows the rebound height of a basketball for each successive bounce....

Find the slope of a line on the coordinate plane. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

In this lesson, students will use input/output tables to explore functions, equations, and graphs.
