Videos: Finding the Inverse Equation

Write the inverse equation for each of the given functions. 3 of the 4 inverse equations will be functions, so use function notation for those.

Videos: Simplifying Radical Expressions (extracting roots)

Even Index (4th and 8th Roots)

Simplify the radical expression when absolute value bars are required for the final answer. This happens for expressions with an even index - like square roots, 4th root, 6th root, etc.

Odd Index (Cube Root)

Absolute value is not required when roots are extracted from an expression with an odd index - like a cube root.

Videos: Sketching Radical Functions (Domain and Range)

This video sketches a a couple square root functions and a cube root function. It also identifies the domain and range as well as talks about vertical stretches and vertical compressions (depending on the value of "a").

Square Root Equation

Solving this square root equation includes the need to factor and has an extraneous solution.

Cube Root Equation

Includes a cube root equation and reviews the need to factor within the problem.
