You can put this solution on YOUR website!
replace F(x) with y
:
y=2x+4.......in order to find the inverse simply exchange y for x and x for y,wherever you find x and y, and solve for y
:
x=2y+4--->subract 4 from each side
:
2y=x-4---> divide by 2
:
replace y by F%5E-1%28x%29
:
highlight%28F%5E-1%28x%29=x%2F2-2%29
