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 the function. f ( x ) = 3 x − 15 2 f\left(x\right)=\frac{3x-15}{2} f ( x ) = 2 3 x − 1 5

f − 1 ( x ) = 15 + 2 x 3 f^{-1}\left(x\right)=\frac{15+2x}{3} f − 1 ( x ) = 3 1 5 + 2 x

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

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

f − 1 ( x ) = 2 3 x − 19 3 f^{-1}\left(x\right)=\frac{2}{3}x-\frac{19}{3} f − 1 ( x ) = 3 2 x − 3 1 9

Find the inverse of the function. f ( n ) = − 4 − 2 5 n f\left(n\right)=-4-\frac{2}{5}n f ( n ) = − 4 − 5 2 n

f − 1 ( n ) = − 5 2 n − 10 f^{-1}\left(n\right)=-\frac{5}{2}n-10 f − 1 ( n ) = − 2 5 n − 1 0

f − 1 ( n ) = − 6 − 5 n 2 f^{-1}\left(n\right)=\frac{-6-5n}{2} f − 1 ( n ) = 2 − 6 − 5 n

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

f − 1 ( n ) = − 2 n − 4 5 f^{-1}\left(n\right)=\frac{-2n-4}{5} f − 1 ( n ) = 5 − 2 n − 4

h ( x ) = − 2 x − 1 − 3 h\left(x\right)=-\frac{2}{x-1}-3 h ( x ) = − x − 1 2 − 3 Find the inverse of the function.

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

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

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

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

Which of the following best describes the graph?

They are reflected over y=x, but they are not both functions.

They are both functions, but not inverse functions.

They are not reflected over y=x, and they are not both functions.
