Question

If f(x) = 1 over 3x − 2 and g(x) = −2x − 1, find (f • g)(9)

19

−18

0

−19

Answer 1

I got -17. ._.

Answer 2

find
\[f(9)\] then
\[g(9)\] then multiply

Answer 3

\[f(9)=\frac{1}{3\times 9-2}=\frac{1}{25}\]

Answer 4

\[g(9)=-2\times 9-1=-19\] so i don't get any of your choices. is this
\[f\times g(9)\] or
\[f\circ g(9)\]

Answer 5

?

Answer 6

is
\[f(x)=\frac{1}{3x-2}\]?

Answer 7

fxg=(-2x-1)/(3x-2)
fxg(9)=(-2*9-1)/(3*9-2)=(-18-1)/(27-2)=-19/25
