Question

Graph the exponential model

y = 3(6)^x Which point lies on the graph?

(-9 2)
(2, 9)
(- 1, - 18)
(1, 18)

Answer 1

Answer: (1, 18)

Explanation:

Test each x, y pair.

Getting to the last one, plug in 1 for the x value.

y = 3 * (6 ^ x)

y = 3 * (6 ^ 1)

y = 3 * 6

y = 18

This matches with (1, 18) so it must lie on the graph.
