Document Summary

Answers without proper evidence of knowledge will not be given credit. Unless otherwise stated, every problem is worth 10 points (making a total of 150 points). Any polynomial can be graphed as a transformation of the graph of y = x2. For any angle r we have that (sin( ) + cos( ))2 = 1. Given any one-to-one function f (x), we can de ne an inverse function f 1(x) such that f 1(f (x)) = x for every x in the domain of f (x). If a > 1 then the function f (x) = ax has a horizontal asymptote on the x-axis. 1 r = 1 + r + r2 + r3 + . If you know any two angles and one side of a triangle, then there is only one possibility for the other sides and angle of the triangle.
