The answer would be D because you are subtracting a positive 17 from a positive 88
Decreasing [-8, -4] increasing [-1, 2]
(look at the slopes)
You can use y = {-1, x ≤ 0 and y = {x - 1, x > 0 as two functions for your piecewise function. The first function will be a horizontal line. The second function will be a straight line with a slope of 1 and y-intecept of -1. Messaged you the graph.
The answer is 3. You do y2-y1 over x2-x1
