The figure below is a square within a square. write an expression for the area of the shaded region.
evaluate the expression from part (a) for x = 4.5
hint: use ^ to show exponents. for example, ft2 can be typed in the answer box ft^2

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.
