The radical equation 2+√2x-3 = √x+7 has a solution set [x= a0} and an extraneous root x = a1.

In the polynomial below, what number should replace the question mark to produce a difference of squares? x2 + ? x - 36

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.
