Question

Find the polynomial function with roots 1, -2, and 5.

Answer 1

f(x) = (x-1)(x+2)(x-5)

Answer 2

technically it shouldn't be the word "the" since there's an infinite choice of polynomials. For example:

f(x) = a * (x-1)^b * (x+2)^c * (x-5)^d

If you say that it must have those results, but could have others, then there are even more possibilities.
