What must be a factor of the polynomial function f(x) graphed on the coordinate plane below? x – 2 x – 1 x + 1 x + 2

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.
