I picked out the ones that I thought all of you should be able to do at this point. (or at least have a good idea of where to start.) They are from the multiple choice section of the test but I did not give you choices (conservation of paper and I thought you could do them on your own). I picked 15 of the 28 in the section. The time limit for the 28 is 55 minutes with NO CALCULATOR! Key points to remember: 1. Unless otherwise specified, the domain of a fimction f is assumed to be the set of all Real numbers 3: for which f (x) is a Real number. 2.

    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.
