Section 2.2: Square Root of a Function
Example 1: pg 80
Linear function vs. Square Root
a) Given f(x) = 3 2x, graph the functions y = f(x) and
a) x y = 3 2x

Note: The domain of consists only those values in the domain of f(x)
for which f(x) ≥ 0
The range of consists of the square roots of the values in the
range of y = f(x) for which is defined.
