Question 279162
I think you want the inverse function of f(x) = -8x + 48


solve for x.


add 8x to both sides of this equation and subtract f(x) from both sides of this equation to get:


8x = -f(x) + 48


divide both sides of this equation by 8 to get:


x = -f(x)/8 + 6


replace x with f^-1(x) and f(x) with x to get:


f^-1(x) = -x/8 + 6


that's your inverse equation.
