Use the rational zero test to list all possible rational zeros of f. Then find rational zeros. F(x)=4x^4-17x^2+4, f(x)=3x^3-5x^2-4x+4, f(x)=6x^3-x^2-13x+8, and finally f(x)=4x^3+7x^2-11x-18.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
