Question

Which set of ordered pairs could be generated by an exponential function?

(0,0), (1, 1), (2, 8), (3, 27)
(0, 1), (1, 2), (2, 5), (3, 10)
(0,0), (1, 3), (2, 6), (3, 9)
(0, 1), (1, 3), (2, 9), (3, 27)

Answer 1

D

Explanation:

Answer 2

(0, 1), (1, 3), (2, 9), (3, 27)

EXPLANATION

The first and third options are completely out because the y-value of an exponential function is never zero.

For the second option the y-values has no geometric pattern or common ratio.

For the last option, we can observe the following pattern

`1 = {3}^(0)`

`{3}^(1) = 3`

`{3}^(2) = 9`

`{3}^(3) = 27`

:

:

`{3}^(x) = y`

The correct choice is the last option
