Khan Academy: Recognizing Functions From Graph

Keep your mathematicians engaged using this group linear functions activity. Each of ten groups receives two graphs with both an image and equation, as well as a "who has" phrase to call out the next graph. Scholars stay on their toes as...

Seeing functions in nature is a beautiful part of mathematics by analyzing the motion of a dolphin over time. Then take a look at the value of a stock and maximize the profit of a new toy. Explore the application of quadratics by...

In this exercise, students practice recognizing functions from graphs. Students receive immediate feedback and have the opportunity to watch a video, get hints, or try questions repeatedly.

Determine whether a given graph represents a function. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

In this exercise, students practice recognizing functions from tables. Students receive immediate feedback and have the opportunity to watch a video, get hints, or try questions repeatedly.

Determine whether a table of values of a relationship represents a function. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Evaluate functions for specific inputs given the graph of the function. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Video about translating between the graph and equation of trigonometric functions. Examples consist of writing the equation a sine function from its graph and graphing a cosine function from its equation. [5:13]

Answer this question to see if understand how to determine a function based on a graph.

Demonstrates solutions to three problems. Problems address understanding of graphs of quadratic equations and translations of graphs of quadratic equations. [11:31]
