Find the domain of f(x)^-1 if f(x)=4x-8 A. x≠ 1/4 B. x≠ -4 C. x≠ 0 D. All real numbers

OpenStudy (johnweldon1993):

f(x)^-1 means the inverse of that function It means that you take your original equation y = 4x - 8 And you switch the 'x' and the 'y'...it will now look like x = 4y - 8 And now you solve for 'y' again...can you do this?
