Answer:
C
Step-by-step explanation:
Substitute the x- coordinate into f(x) and if the value is equal to the y- coordinate of the point then the point is on the graph.
A (0, 18)
f(0) = 3 × [tex]6^{0}[/tex] = 3 × 1 = 3 ≠ 18 ← not on graph
B (18, 1 )
f(18) = 3 × [tex]6^{18}[/tex] ≠ 1 ← not on graph
C (1, 18 )
f(1) = 3 × [tex]6^{1}[/tex] = 3 × 6 = 18 ← on the graph
D (0, 0 )
f(0) = 3 × [tex]6^{0}[/tex] = 3 × 1 = 3 ≠ 0 ← not on graph
