In each expression below, identify the coefficient, constant, and variable. a) 4v + 7
b) 10u – 8
c) –3.6 – 1.8w
d) –6.1 – 2.2x

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.
