Let C(x) = 9x + 950 and R(x) = 22x.
(a) Write the profit function P(x).
P(x) =
X

this doesn't make sense lol

hi how are you doing today, if you need just ask me.

step-by-step explanation:

answer: hence, function will be

7 would be on the x-axis which is the horizontal line on the graph

84 would be on the y-axis which is the vertical line on the graph
