5-7 Radical Functions Warm Up
Identify the domain and range of each function.
1. f(x) = x2 + 2
2. f(x) = 3x3
Use the description to write the quadratic function g based on the parent function f(x) = x2.3. f is translated 3 units up.
4. f is translated 2 units left.

5-7 Radical Functions The graphs of radical functions can be transformed by using methods similar to those used to transform linear, quadratic, polynomial, and exponential functions. This lesson will focus on transformations of square-root functions.
