2. Graph Square Root Functions
Section 11.1

3. Objectives: Graph square root functions
Graph square root functions with transformations

4. Key Vocabulary: Radical expression Radical function
Square root function
Parent square root function

5. Radical expressions, radical functions, and square root functions
A radical expression is an expression that contains a radical, such as a square root, cube root, or other root. A radical function contains a radical expression with the independent variable in the radicand. Examples: If the radical is a square root, then the function is called a square root function.
