Section 3.2 Power Functions A function f is a power function if it has the following form: f ( x )= ax n for some positive integer n . The number n is the degree of the power function. Example. f ( x )= - 3 x 4 is a power function of degree 4. Example. f ( x )=3 x 3 is a power function of degree 3. Graphs of y = x n , with n odd, are symmetric about origin and appear as follows: –2 –1 0 1 2 –2 –1 1 2 Graphs of y = x n , with n even, are symmetric about
