2.2 The Graph of a Function
When a function is defined by an equation in x and y, the

Suppose that we wish to solve the quadratic equation
x2 = p

This gives the following method.
Square Root Method: If x2 = p and p 0, then x =
p or x = p.
Example 1. Solve x2 = 16.
Completing the square is a process that takes an
