For this case we have the following quadratic functions:
Revenue:
Cost:
Then, we observe that the profit is given by the following mathematical relationship:
Substituting values we have:
Making the corresponding calculations we have:
Answer:
An expression that represents the profit is:
A parallel equation (when graphed) will have the same slope, but a different y-intercept.
As long as you keep y = -x + b, you can input anything for b to solve this question.
Given:
y = -x - 5
Equation of a parallel line:
y = -x + 6, y = -
x + 1,356, y = -
x - 8, etc
Example answer you can use:
y = -x - 8
