Question

3. I need help with question in the attached picture!

Answer 1

p

`{f}^( - 1) (x) = 3x + 4`

Step-by-step explanation

The line r has equation,

`f(x) = (x - 4)/(3)`

The line that represents

`{f}^( - 1)`

is p.

To find the equation of p, we let

`y = (x - 4)/(3)`

We now interchange x and y.

`x= (y - 4)/(3)`

We solve for y,

`3x=y - 4`

`y = 3x + 4`

Therefore

`{f}^( - 1) (x) = 3x + 4`
