Explain step-by-step how to simplify -5(2x – 3y + 6z – 10).

What is the factor form of x^2-9x+14

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.
