Explanations:
According to the given statement, the number of product lies on the x-coordinate axis while the the overall profit margin represents the y-coordinate axis.
The interpretation of the vertex (75,10000) shows that the maximum profit is 10,000dollars is reached when 75 items are produced. The vertex shows the maximum point on the curve.
For the x-intercepts at x = 0 and x = 150. Since the x-intercept is the point where there is no profit margin (y = 0), hence:
The x-intercept (0, 0) tells us that the profit will be 0 dollars when 0 items are produced,
The second root (150, 0) says once 150 items are made, the company is no longer making any profit.
