I'm trying to find all zeros by either factoring and/or using the quad. formula for:
f(x) x^3 - 2x^2 - x + 2
Next, I'm trying to show that f(g((x)) = x and g(f(x)) = x for all x:
f(x) = 2x^3 + 1 or g(x) = [cube root] (x-1/2)
Thanks in advance for any help :)
Just figured out both problems. Thanks for all the help!
