Answer
(-2,$\frac{1}{8}$)(0,$\frac{1}{2}$)(2,2)
Work Step by Step
You have y=$\frac{1}{2}$ $\times$ $2^{x}$.Plug in the values x=-2,0,2 to find the y-value.
X=-2
y=$\frac{1}{2}$ $\times$ $2^{-2}$
y=$\frac{1}{2}$ $\times$ $\frac{1}{4}$
y=$\frac{1}{8}$
x=0
y=$\frac{1}{2}$ $\times$ $2^{0}$ -any number raised to 0 always equals 1-
y=$\frac{1}{2}$ $\times$ 1
y=$\frac{1}{2}$
x=2
y=$\frac{1}{2}$ $\times$ $2^{2}$
y=$\frac{1}{2}$ $\times$ 4
y=2
