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

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

f − 1 ( x ) = 3 x − 2 f^{-1}(x)=3x-2 f − 1 ( x ) = 3 x − 2

f − 1 ( x ) = 2 + 3 x f^{-1}(x)=2+3x f − 1 ( x ) = 2 + 3 x

Find the inverse of f ( x ) = 1 x f(x)=\frac{1}{x} f ( x ) = x 1 .

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

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

Determine which statement is true about the following relation {(2, 3), (4,5), (6,9), (1,9)}

The relation is a function but the inverse is not a function.

The relation is not a function but the inverse is a function.

The relation is a function and the inverse is a function.

The relation is not a function and the inverse is not a function.

Find the inverse of f ( x ) = − 5 x − 7 f\left(x\right)=-5x-7 f ( x ) = − 5 x − 7

f − 1 ( x ) = x + 7 − 5 f^{-1}\left(x\right)=\frac{x+7}{-5} f − 1 ( x ) = − 5 x + 7

f − 1 ( x ) = 5 x + 7 − 7 f^{-1}\left(x\right)=\frac{5x+7}{-7} f − 1 ( x ) = − 7 5 x + 7

f − 1 ( x ) = x + 5 7 f^{-1}\left(x\right)=\frac{x+5}{7} f − 1 ( x ) = 7 x + 5

f − 1 ( x ) = 7 − 5 + x f^{-1}\left(x\right)=\frac{7}{-5+x} f − 1 ( x ) = − 5 + x 7
