7-5 Solving Square Root Equations

A radical equation is an equation that has a variable in a radicand (or variable with a fractional exponent.)

If the radical has index 2, the equation is a square root equation.

To solve a radical equation, isolate the radical expression, then raise both sides of the equation to the same power.

7-7 Inverse Functions

Since an inverse exchanges x values with the y values, to find an inverse of an equation you can interchange x and y, and then solve the equation for y.
