Step-by-step explanation:
<em>Refer to attached graph.</em>
<em>It i</em>ncludes the points and a best fit line produced by a graphing calculator.
- 17. The scatter plot is attached
- 18. There is a positive slope. Number of field goal attempts increase as minutes played increase.
- 19. The point is plotted: 2500 minutes gives about 880 field goal attempts.
The function is graphed as shown below
Part A:
We use the formula
to find the vertex of the function. A quadratic function of the form of 
and equating this form to the given function 
, we have
and 
.
Substituting
and 
into the vertex formula, we have
, as shown in the graph
This calculation means that the highest profit is achieved when the number of photo printed equals to ten photos
Part B:
We can find solution to this equation by factorising
and 
, as shown in the graph
The two values means that the company makes no profit when they either produce 5 or 15 photos
Part A:
