The length of a rectangle is 7 1/2 inches and the width is 2 3/4 inches. what is the ratio, using whole numbers, of the length to the width?

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.
