1. Given the function f(x) = 2x²+ 4x - 3, if x = -1, what is f(x)? What point is on the graph of f?
2. Assume that the long-run total cost function is:

LRTC = 2000Q - 160Q²+ 4Q³

Write the equation for the long-run average cost (LRAC).

3. Find f(1) when f(x) = (x²- 8) /(x - 2)

4. A truck rental company rents a moving truck one day by charging $25 plus $0.09 per mile. Write linear equation that relates the cost C, in dollars, of renting the truck to the number x of miles driven. What is the cost of renting the truck if the truck is driven 200 miles?
