Which point is on the graph of f(x) = 3 x 5^x?

C

Step-by-step explanation:

To determine which point lies on the graph, substitute the x-coordinate into f(x) and if the value is equal to the y-coordinate then the point is on the graph

A (15, 1)

f(15) = 3 × ≠ 1 ← not on graph

B (0, 15)

f(0) = 3 × = 3 × 1 = 3 ≠ 15 ← not on graph

C (1, 15)

f(1) = 3 × = 3 × 5 = 15 ← lies on graph

D (0, 0)

f(0) = 3 × = 3 × 1 = 3 ≠ 0 ← not on graph
