Question 483944: How do you find the inverse of f(x)= 1/(x^2) or f(x)=1/(x^3)?
I don't really have a problem with finding inverses but I can't figure out these two. I usually switch x and y, so can anyone explain it to me in that manner? A detailed answer is really what I need. Thank you, in advance!

How do you find the inverse of f(x)= 1/(x^2) or f(x)=1/(x^3)?
:
y =
swap x and y and then find y
x =
multiply both sides by y^2
xy^2 = 1
divide both sides by x
y^2 =
Find the square root of both sides
y =
:
f(x) = 1/(x^3) is the same except its the cube root of 1/x
