What is the total surface area?

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.

Solve the inequaliy: (x^2+2)(x−2)^2(6−2x)> 0
