Mileage/graph
I tried this and needed to graph. But, I want to find out what I did incorrect. Suppose that a car rental agency gave you the following choices. Option A: \$30 per day plus 40 cents per mile. Option B: flat \$50 per day (a) Write equations for cost per day c for options A and B...

Can you use algebra to find a quadratic equation if your know the coordinates of just ONE point on its graph? Can you use algebra to find a quadratic equation if your know the coordinates of just TWO points on its graph? If so, what information is needed?

Calculus I
Sketch the graph of f by hand and use your sketch to find the absolute and local maximum and minimum values of f. 18. f(x) = 1/x , 1 < x < 3 I can graph it just fine, but for my answer I got that the function has none of the above. Is this correct?
