Which of the following functions has a factor of x + 1? O f(x) = x3 – 11x2 + 20x + 33
O f(x) = x3 – 13x2 + 44x – 31
O f(x) = x3 – 13x2 + 44x – 32
O f(x) = x3 – 11x2 + 20x + 32

Convert the cartesian equation (x 2 + y 2)2 = 4(x 2 - y 2) to a polar equation. choices: r4 = -4r2 r2 = 4cos2θ r2 = 4sin2θ
