Question

Ramon is graphing the function f(x) = 3(4)x. He begins by plotting the initial value. Which graph represents his initial step?

On a coordinate plane, the point (0, 3) is graphed.
On a coordinate plane, the point (0, 4) is graphed.
On a coordinate plane, the point (3, 0) is graphed.
On a coordinate plane, the point (4, 0) is graphed.

Answer 1

f(0) = 3·4^0 = 3·1 = 3, so the y‑intercept is (0, 3). Thus the first point graphed is (0, 3).
