Answer
f(-2)=0.16,f(0)=1,f(2)=6.25
Work Step by Step
You have f(x)=$2.5^{x}$.Plug in x=-2,x=0,x=2 to find the y-values:
x=-2:
f(-2)=$2.5^{-2}$
f(-2)=0.16
x=0:
f(0)=$2.5^{0}$ -any number raised to 0 always equals 1-
f(0)=1
x=2:
f(2)=$2.5^{2}$
f(2)=6.25
You have f(-2)=0.16,f(0)=1,f(2)=6.25.Plot the pairs and connect them to make a graph.
