Question

Exponential function f is represented by the table.

x -2 -1 0 1 2 f
(x) -62 -30 -14 -6 -2

Function g is represented by the equation.
g(x) = -20 (1/2)^x + 10

Which statement correctly compares the two functions on the interval [-2, 1]?

A. Only function f is increasing, and both functions are negative.
B. Only function f is increasing, and only function f is negative.
C. Both functions are increasing, but function g increases at a faster average rate.
D. Both functions are increasing, but function f increases at a faster average rate.

Answer 1

I believe the correct answer to this question is D.

Explanation:

You can use Desmos (graphing calculator) to graph the equation to verify it. :)
