Use the Rational Zeros Theorem to write a list of all possible rational zeros of the function.
f(x) = -2x4 + 4x3 + 3x2 + 18
f(-x) = -2x^4 - 4x^3 + 3x^2 + 18
-----
f(x) has 1 change in sign implies # of positive Real Roots is 0 or 1.
---
f(-x) has 1 change in sign implies # of negative Real Roots is 0 or 1
