Answer
f(-1)=$\frac{1}{8}$, f(2)=8, f(3)=32
Work Step by Step
You have f(x)=$\frac{1}{2}$ $\times$ $4^{x}$.Plug in x=-1,2,3 to solve for Y.
x=-1:
f(-1)=$\frac{1}{2}$ $\times$ $4^{-1}$
f(-1)=$\frac{1}{2}$ $\times$ $\frac{1}{4}$
f(-1)=$\frac{1}{8}$
x=2
f(2)=$\frac{1}{2}$ $\times$ $4^{2}$
f(2)=$\frac{1}{2}$ $\times$ $\frac{16}{1}$
f(2)=8
x=3
f(3)=$\frac{1}{2}$ $\times$ $4^{3}$
f(3)=$\frac{1}{2}$ $\times$ $\frac{64}{1}$
f(3)=32
