### show graph ofr profit equation

Can someone point me in the right direction for this problem?
6. Show a graph of the profit equation. Be sure to label the horizontal and vertical axes.
• Label the y-intercept with an ordered pair of numbers. Explain these values in the context of the problem.
• Label both x-intercepts with ordered pairs of numbers, approximating values to the nearest tenth. Explain these values in the context of the problem.
• Label the vertex with an ordered pair of numbers. Explain these values in the context of the problem.
I'm guessing X is items produced and Y is profit? So all numbers should be in the upper right quadrant of the graph where positive X and Y numbers reside?

profit of 0 = \$0
profit of 5 = \$1518
profit of 10 = \$2619
profit of 15 = \$3560
profit of 20 = \$4341
profit of 25 = \$4962
profit of 30 = \$5423
profit of 35 = \$5724
profit of 40 = \$5865
profit of 42 = \$5876.6
profit of 45 = \$5846
profit of 50 = \$5667
profit of 55 = \$5328
profit of 60 = \$4829
profit of 65 = \$4170
profit of 70 = \$3351
profit of 75 = \$2372
profit of 80 = \$1233
profit of 84 = \$206.6
profit of 84.7 = 16.45
profit of 84.8 = -10.97
profit of 85 = \$-66

I believe the Y intercept is 0 profit (0, 0)
I believe the first X intercept is 0 items (0, 0), with the second being 84.7 items (84.7, 0)
I believe the vertex is 42, 5876.6

Are you given an actual equation, or are you supposed to be guessing from a list of points? Also, in the listing of points that you provide, what do you mean by statements such as "profit of 0 = \$0"?

Thank you!
