A. Plot the data for the functions f ( x ) and g ( x ) on a grid.

x − 2 − 1 0 1 2 f ( x ) 1 16 1 4 1 4 16

x − 1 0 1 2 3 g ( x ) 3 4 5 6 7

b. Identify each function as linear, quadratic, or exponential, and use complete sentences to explain your choices.

c. Describe what happens to the function values in each function as x increases from left to right.

d. At what value(s) of x are the function values equal? If you cannot give exact values for x , give estimates.
