Answer
f(-1)=4.21,f(2)=3.61,f(3)=3.43
Work Step by Step
You have f(x)=4 $\times$ $0.95^{x}$.Plug in x=-1,2,3 to solve for Y.
x=-1:
f(-1)=4 $\times$ $0.95^{-1}$
f(-1)=4 $\times$ 1.05
f(-1)=4.21
x=2
f(2)=4 $\times$ $0.95^{2}$
f(2)=4 $\times$ 0.9
f(2)=3.61
x=3
f(3)=4 $\times$ $0.95^{3}$
f(3)=4 $\times$ 0.85
f(3)=3.43
