Answer: B) y = 2 · 3ˣ

Step-by-step explanation:

We can see that (2, 18) is a point on the graph.

Plug it into the equations to see which one make a true statement.

A) y = 1 · 3ˣ

18 = 1 · 3²

18 = 1 · 9

18 ≠ 9

B) y = 2 · 3ˣ

18 = 2 · 3²

18 = 2 · 9

18 = 18 This works!

C) y = 3 · 2ˣ

18 = 3 · 2²

18 = 3 · 4

18 ≠ 12

D) y = 4 · 3ˣ

18 = 4 · 3²

18 = 4 · 9

18 ≠ 36
