Question

If f(x) = 5x − 3, which expression represents its inverse function?

Answer 1

i dont thins that the answer ...

Explanation:

Answer 2

`f ^(-1)(x)=(x+3)/(5)`

Explanation:

To find the inverse of a function f (x) follow the steps below:

1) Make y = f (x)

`y= 5x - 3`

2) Solve for the variable x

`y+3= 5x - 3+3`

`y+3= 5x`

`x=(y+3)/(5)`

3) Exchange the variable x with the variable y

`y=(x+3)/(5)`

4) Make
`y = f ^(-1)(x)`

`f ^(-1)(x)=(x+3)/(5)`

Finally, the inverse of the function f (x) is:
`f ^(-1)(x)=(x+3)/(5)`
