If f ( x ) = 1 x f\left(x\right)=\frac{1}{x} f ( x ) = x 1 and g ( x ) = 3 x + 2 g\left(x\right)=3x+2 g ( x ) = 3 x + 2 find f ( g ( x ) ) f\left(g\left(x\right)\right) f ( g ( x ) )

1 3 x + 2 \frac{1}{3x+2} 3 x + 2 1

1 3 x + 2 \frac{1}{3x}+2 3 x 1 + 2

Find the inverse f(x)=2x-2

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

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

f − 1 ( x ) = − 7 3 x − 20 3 f^{-1}\left(x\right)\ =\ \frac{-7}{3}x-\frac{20}{3} f − 1 ( x ) = 3 − 7 x − 3 2 0

f − 1 ( x ) = 2 5 x − 2 f^{-1}\left(x\right)\ =\ \frac{2}{5}x-2 f − 1 ( x ) = 5 2 x − 2

What does it mean to find the inverse of a function?

the x's and y's are divided by 2

the x's and y's are made negative

Find the inverse of f(x) = -4x - 12

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

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

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

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