After 3 hours, a popcorn stand had earned a profit of $25. After 6 hours, the profit was $70. Assuming a linear function, write an equation in the form y=mx+b that shows the revenue earned for selling popcorn for x hours.

Which is f(5) for the function –2x2 + 2x - 3?

How can i differentiate this equation?
