< PREVIOUS QUESTIO
Let a = x2 + 4. Rewrite the following equation in terms of a and set it equal to zero.
(x2 + 4)2 + 32 = 12x2 + 48

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.
