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
