Square Root Functions A square root function is a function that contains a variable inside a square root. The inverse of a quadratic function is a square root function only if the range is restricted to nonnegative numbers.

**Graphing Square Root Functions**

Set the radicand ≥ 0, and solve for x. This is the domain. Set up a T-table that starts with the x-value you found in step 1. Plot the points from the T-table and connect the dots.
