The following function is given. f(x)=x³5x² - 4x + 20 a. List all rational zeros that are possible according to the Rational Zero Theorem. 1,1,2,2,20,20,5, -5,10,- 10,4,-4 b. Use synthetic division to test several possible rational zeros in order to identify one actual zero. One rational zero of the given function is 2. c. Use the zero from part (b) to find all the zeros of the polynomial function. The zeros of the function f(x) = x3 - 5x2 - 4x + 20 are
