A bakery bakes small, medium and large pies. The ratio small : medium : large is 3:5:2.
One day 460 medium pies are baked.
Work out how many small pies are baked.

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.
