Question

F(x) = 3(3x + 4)
The inverse

Answer 1

Explanation:

find the inverse of the function y=9x+12

To find the inverse function, swap x and y, and solve the resulting equation for x.

If the initial function is not one-to-one, then there will be more than one inverse.

So, swap the variables: y=9x+12 becomes x=9y+12.

Now, solve the equation x=9y+12 for y.

`f^(-1)`(x) = (x-12)/9

y=(x−12)/9
