Answer:

f(-2) + 9 is 19

Step-by-step explanation:

$f(x) = - 3x - 2$

when x is -9:

$f( - 2) = - 3( - 2) - 2 \\ f( - 2) = 10$

sum up with 9, f(-2)+9:

$f( - 2) + 9 = 10 + 9 \\ = 19$

\\\\\\
\stackrel{common~factor}{3^n}(3^2-1)=8\cdot 3^n\implies 3^2-1=\cfrac{8\cdot \underline{3^n}}{\underline{3^n}}\implies 3^2-1=8
