-9 - 9=-18

Answer 3

jus sub x=-9
so the answer will be 0.5^-18=262144
A

Answer 4

that's the exponent.
it would be

\(\LARGE\color{blue}{ \bf f(-9)=0.5^{-9-9} }\)

\(\LARGE\color{blue}{ \bf f(-9)=0.5^{-18} }\)

\(\LARGE\color{blue}{ \bf f(-9)=\frac{1}{0.5^{18}} }\)

Answer 5

f(-9)=0.5^(-9-9)
=0.5^(-18)
=262144 (A)
