o
a. y + 9 = 2(x + 1)
o
b. y- 9 = -2(x - 1)
o
c. y+9 = -2(x+1)
o
d. y-9 = 2(x - 1)

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.
