Things you should know before starting calculus! Evaluate the function. 1) Find f(k - 1) when f(x) = 5x 2 - 3x + 7. Graph the function. 2) f(x) = 2x + 7, 3x 2 - 1, for x <- 3, for - 3 < x < 4 - 3 for x > 4 For #3 and 4, give the domain and range using interval notarion. 3) f(x) = - x - 7 4) f(x) = 1 x 2 + 1x - 12 5) The demand function for the newest IPOD is D(p) = - .375p + 80 . a) Graph (and label) D(p) and R(p). b) Find the price to maximize revenue. Find the max revenue. c) If 70 units are desired by the consumer, what is the unit price? d) Find the quantity to maximize revenue. Solve the problem. 6) A certain viral infection causes a fever that typically lasts 6 days. A model of the fever (in Farenheit degrees) on day x is F(X) = - 2/3 X 2 + 14/3 X + 96 where the domain for x is [0,6]. a) According to this model, on what day should the maximum fever occur? Explain what the answer means. b) Graph and label the function. 7) Given: D(x) = - x 2 + 2x + 100, S(x) = 8x + 20 Find the Equilibrium Point. (Ignore the negative x value).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
