3. In the diagram below, altitude NQ has been drawn to hypotenuse MP in right triangle MNP. Which of the following would equal the ratio of MN to NQ?

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.
