The inverse of a function is obtained by making x the subject of the formular of the function.
Given the function

the inverse of the function is obtained as follows:

Given the function
[tex[f(x)=x+7[/tex]
the inverse of the function is obtained as follows:

Given the function

the inverse of the function is obtained as follows:

Given the function

the inverse of the function is obtained as follows:
This can be solved by using the 30 60 90 triangle. The 30-60 side is equal to 2x, here it is 2x=18. The 60-90 side is equal to x. So this side is 18/2=9. The 30-90 side is by the way equal to the root of x, so here the root of 18
