Which is the BEST estimate of the average rate of change for the function graphed, over the interval 1 ≤ x ≤ 3?

A) 2

B) 3

C) 4

D) 6

Answer 1

-3

Explanation:

3 is the average rate of change for the exponential graph shown over the interval 1 ≤ x ≤ 3.

Start by determining the two distinct points: (1, 2) and (3, −4).

Therefore,

Δf(x)

Δx

=

−4 − 2

3 − 1

=

−6

2

= −3

Answer 2

The answer is B) 3

Explanation:

The reason why is because 1 is less than OR equal to x and 3 is less than or equal to x and is x = 3 then it fits both descriptions the best.
