I am suposed to solve for x if the FUNCTION is equal to 5.

calculus
well it said that in the book but it wants you to solve for x IF the function is equal to 5.

calculus
The equation of the function is: f(x)=4-2(x-6)^1/3, for x not equal to 5 calculate precisely the value of f(x). so I got this: 5=4-2(x-6)^1/3 1=-2(x-6)^1/3 (-1/2)=(x-6)^1/3 (-1/2)^3=(x-6) -.125=x-6 now the next step is suposed to be this but I don't understand how they got...
