a. The terms are
b. The domain of the function is given as 1 ≤ x ≤ 4. The graph is a discrete graph
The term in the linear function m = 200 − 50v interpreted as
200 = money set aside for buying video games
50 = cost per video game
v = number pf video games
m = total amount spent on video games
The number refers to all the possible input values, this value as regard this context is when the money left for video game is finished.
the input value is v, the domain is solved as follows
200 - 50v = 0
50v = 200
v = 200/50
v = 4
The maximum number is 4 while the minimum is just above 0 or from 1 hence the domain is
1 ≤ x ≤ 4
the graph is attached
