10Square Root Functions and Inequalities Section 7-9
11Square Root FunctionsA 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.
12Graphing 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.
13Example 1Graph the function. State the domain and range.
14You-Try #1Graph the function. State the domain and range.
