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

devlian [24]

ANSWER

(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
