1. Problem Description

We are asked to plot the function f(x)=4(12)xf(x) = 4 \cdot (\frac{1}{2})^x on the provided graph.

2. Solution Steps

We need to evaluate the function at several points to plot it.
x = -2: f(2)=4(12)2=4(2)2=44=16f(-2) = 4 \cdot (\frac{1}{2})^{-2} = 4 \cdot (2)^2 = 4 \cdot 4 = 16
x = -1: f(1)=4(12)1=4(2)1=42=8f(-1) = 4 \cdot (\frac{1}{2})^{-1} = 4 \cdot (2)^1 = 4 \cdot 2 = 8
x = 0: f(0)=4(12)0=41=4f(0) = 4 \cdot (\frac{1}{2})^{0} = 4 \cdot 1 = 4
x = 1: f(1)=4(12)1=412=2f(1) = 4 \cdot (\frac{1}{2})^{1} = 4 \cdot \frac{1}{2} = 2
x = 2: f(2)=4(12)2=414=1f(2) = 4 \cdot (\frac{1}{2})^{2} = 4 \cdot \frac{1}{4} = 1
x = 3: f(3)=4(12)3=418=12=0.5f(3) = 4 \cdot (\frac{1}{2})^{3} = 4 \cdot \frac{1}{8} = \frac{1}{2} = 0.5
We can plot these points: (-2, 16), (-1, 8), (0, 4), (1, 2), (2, 1), (3, 0.5)

3. Final Answer

The function is plotted by connecting the points (-2, 16), (-1, 8), (0, 4), (1, 2), (2, 1), (3, 0.5) on the provided graph.
