Instructions for a craft project say that the length of a piece of red ribbon should be 7 inches less than the
length of a piece of blue ribbon.
How long is the red ribbon if the length of the blue
ribbon is:
A. 10 inches?
B. 27 inches?
C. x inches?

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.
