Question

For the graphed function f(x) = (4)x - 1 + 2, calculate the average rate of change from x = 2 to x = 4.

Answer 1

Answer:

D: 30

Step-by-step explanation:

f(x) = 4^(x-1) + 2

f(4) = 4^(4-1) + 2

= 4³ + 2 = 66

f(2) = 4^(2-1) + 2

= 4¹ + 2 = 6

Average rate of change:

(66 - 6)/(4 - 2)

60/2

30

Answer 2
