Yo sup??
y=3x+12
y-12=3x
x=y/3 - 4
f(y)=y/3 - 4
or
f(x)=x/3 - 4
where f(x) is the inverse of y.
Hope this helps
The inverse of the function is y = (x-12)/2
The inverse of a function
Given the function y = 3x + 12
Replace y with x
x = 3y + 12
Make y the subject of the formula:
3y = x - 12
y = (x-12)/2
Hence the inverse of the function is y = (x-12)/2
