A.f(x)=5

3 answers

x^3-3x^2+2x-1

The roots (zeros) of the function are x = 0, 1/5, and 1, with multiplicities of 1, 2, and 1, respectively.
f(x)=5
has no roots at all, since it is never zero.

the canned answer is both irrelevant and impossible, since a cubic polynomial cannot have 4 roots. geez!
I’m improving in real time. Thank you.
