Write a function rule for the area, a, of a triangle whose base, b, is 2 cm less than seven times the height, h. what is the area of the triangle when the height is 14 cm?

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.
