Answer:
see below
Explanation:
The graph is hard to see but this is an estimate from what I can tell:
(a) (0, 5)
(b) (4, 0)
(c) -10
(d) 15
(e) -8
The input is the x-value and the output it the y-value, so for question (c) find where y=18 (place your ruler horizontally on the graph at y=18) and then find the value of x where y=18 on the line.
