This is really not a Math test question bt could be one - like cuz it relates to whatever is being asked in math...
1. If f '(x) and g '(x) exist and f '(x) > g '(x) for all real [unparseable or potentially dangerous latex formula]. then the graph of [unparseable or potentially dangerous latex formula] and the graph of [unparseable or potentially dangerous latex formula]
A. intersect exactly once
B. intersec no more than once
C. do not intersect
D. could intersect more than once
E. have a common tangent at each point of intersection
2. What is the amplitude of the function [unparseable or potentially dangerous latex formula] ?
