You may have noticed that we have been evaluating or "plugging-in" lots of numbers to find the corresponding y-values. We have been doing this to find points on the graph (x, y). This process can be streamlined using function notation.
Graph the given linear function.
a. Find a cost function C(x) that models this business.
b. Find a revenue function R(x) that models this business.
c. Find the profit function P(x) using your functions above.
d. Find the profit when 1000 programs are produced and sold.
e. Find the number of programs that must be sold to break even.
