Question

The inverse of f(x)=4x+5

Answer 1

To find the inverse of a function switch the place of y (aka f(x) ) with x. Then solve for y.

Original equation:

y = 4x + 5

Switched:

x = 4y + 5

Solve for y by isolating it:

x - 5 = 4y + 5 - 5

x - 5 = 4y

(x - 5)/4 = 4y/4

$\frac{1}{4}x-\frac{5}{4} = y$

Hope this helped!
