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