Let A be the set of factors of 20, B be the set of factors of 30, C be the set of factors of 40, and D be the set of factors of 50.
The universal set is {1, 2, 3, 4, 5, 6, 8, 10, 15, 20, 25, 30, 40, 50).
1.
Write sets A through D using set notation.

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.

Which shows the first equation written in slope-intercept form? 1/2 (2y + 10) = 7x
