Two functions are represented in different formats.

function 1:

let x = number of hours worked

let y = total pay in dollars

y = 20x + 15

function 2: a babysitting club charges a $25 flat rate and $10 for each hour.

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.
