The table below represents a function. which of the following equations could be its function rule? x y 0 0 1 -3 3 -9 -2 6 a. y = -3x b. y = x c. y = 3x d. y= x/-3

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.
