When solving f(g(x)) you work in what order?

It doesn't matter what you solve first, just pick your favorite letter.

Find the inverse of f ( x ) = 3 x + 2 f\left(x\right)=3x+2 f ( x ) = 3 x + 2

f − 1 ( x ) = x − 2 3 f^{-1}\left(x\right)=\frac{x-2}{3} f − 1 ( x ) = 3 x − 2

f − 1 ( x ) = x − 3 2 f^{-1}\left(x\right)=\frac{x-3}{2} f − 1 ( x ) = 2 x − 3

f − 1 ( x ) = 3 x 2 f^{-1}\left(x\right)=\frac{3x}{2} f − 1 ( x ) = 2 3 x

f − 1 ( x ) = 2 + x 3 f^{-1}\left(x\right)=\frac{2+x}{3} f − 1 ( x ) = 3 2 + x

Find the inverse of f ( x ) = − 3 4 x + 5 f\left(x\right)=-\frac{3}{4}x+5 f ( x ) = − 4 3 x + 5

f − 1 ( x ) = − 4 3 ( x − 5 ) f^{-1}\left(x\right)=-\frac{4}{3}\left(x-5\right) f − 1 ( x ) = − 3 4 ( x − 5 )

f − 1 ( x ) = 5 ( x − 4 3 ) f^{-1}\left(x\right)=5\left(x-\frac{4}{3}\right) f − 1 ( x ) = 5 ( x − 3 4 )

f − 1 ( x ) = − 3 4 ( x − 5 ) f^{-1}\left(x\right)=-\frac{3}{4}\left(x-5\right) f − 1 ( x ) = − 4 3 ( x − 5 )

f − 1 ( x ) = − 5 ( x − 3 4 ) f^{-1}\left(x\right)=-5\left(x-\frac{3}{4}\right) f − 1 ( x ) = − 5 ( x − 4 3 )

Find the inverse of f ( x ) = 4 x − 9 f\left(x\right)=4x-9 f ( x ) = 4 x − 9

f − 1 ( x ) = 1 4 x + 9 4 f^{-1}\left(x\right)=\frac{1}{4}x+\frac{9}{4} f − 1 ( x ) = 4 1 x + 4 9

f − 1 ( x ) = − 1 4 x + 9 4 f^{-1}\left(x\right)=-\frac{1}{4}x+\frac{9}{4} f − 1 ( x ) = − 4 1 x + 4 9

f − 1 ( x ) = 1 4 x − 9 4 f^{-1}\left(x\right)=\frac{1}{4}x-\frac{9}{4} f − 1 ( x ) = 4 1 x − 4 9

f − 1 ( x ) = 4 x + 36 f^{-1}\left(x\right)=4x+36 f − 1 ( x ) = 4 x + 3 6
