Question

Which ordered pairs lie on the graph of the exponential equation

f(x) = 25(2.2)^x?
Select EACH correct answer.

[] (0, 0)
[] (0.5, 37.08)
[] (1, 55)
[] (2, 121)

Answer 1

• B, C, D

Explanation:

The equation is:

• f(x) = 25(2.2)^x

Plug in the values and verify if correct:

A. (0, 0)

• f(0) = 25(2.2)^0 = 25 ≠ 0, No

B. (0.5, 37.08)

• f(0.5) = 25(2.2)^0.5 = 37.08, Yes

C. (1, 55)

• f(1) = 25(2.2)^1 = 55, Yes

D. (2, 121)

• f(2) = 25(2.2)^2 = 121, Yes
