Factor the polynomial 3x4 – 2x2 + 15x2 – 10 by grouping. Which product is the factored form of the polynomial

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.
