Ramon is graphing the function f of x is equal to 3 times 4 to the x th power He begins by plotting the initial value. Which graph represents his initial step?

Answer

A

Image with description A coordinate plane with a single marked point. The x-axis is labeled from negative 5 to 5 in increments of 1. The y-axis is labeled from negative 3 to 8 in increments of 1. A point is marked and labeled 4 comma 0 on the x-axis.

B

Image with description A coordinate plane with a single marked point. The x-axis is labeled from negative 5 to 5 in increments of 1. The y-axis is labeled from negative 3 to 8 in increments of 1. A point is marked and labeled 0 comma 3 on the y-axis.

C

Image with description A coordinate plane with a single marked point. The x-axis is labeled from negative 5 to 5 in increments of 1. The y-axis is labeled from negative 3 to 8 in increments of 1. A point is marked and labeled 3 comma 0 on the x-axis.

D

Image with description A coordinate plane with a single marked point. The x-axis is labeled from negative 5 to 5 in increments of 1. The y-axis is labeled from negative 3 to 8 in increments of 1. A point is marked and labeled 0 comma 4 on the y-axis.

Explanation

The initial value is the function's value when x = 0. Substituting gives f(0) = 3 × 4⁰ = 3 × 1 = 3, so Ramon should plot the point (0, 3). Choice A shows that point on the y-axis.
