Khan Academy: Evaluating Function Expressions

Evaluate expressions that contain function notation, given the functions' graphs. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

Evaluate expressions that contain function notation, given the functions' graphs.

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.

In this video lesson students evaluate a function expression.

Evaluate functions for specific inputs given the formula of the function. Functions are written using function notation.

A video exploring whether a function is represented by a given set of points. [4:06]

This video introduces to students what a variable, expression, and equation is. It also demonstrates how to substitute values for variables and evaluate expressions and equations using substitution. [6:55]

Evaluate numerical radical expressions using the properties of exponents. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Evaluate numerical radical expressions using the properties of exponents.

The final segment in the Khan Academy's series on function inverses. Similar to the previous video, this segment does another example for finding the inverse of a quadratic function. Again the instructor explains the need for restraints...
