Question

The table of values represents an exponential function ​f(x). What is the average rate of change over the interval −2≤x≤2 ? Enter your answer, as a decimal rounded to the nearest hundredth, in the box. x f(x) −3 8 −2 4 −1 2 0 1 1 12 2 14 3

Answer 1

2.50

Explanation:

Answer 2

2.50

Explanation:

The average rate of change over the interval −2≤x≤2 is:

(f(2) − f(-2)) / (2 − -2)

From the table, we see that f(2) = 14 and f(-2) = 4.

(14 − 4) / (2 − -2)

10 / 4
