f(x)>0		The outputs of f(x) are positive or the graph of f(x) is above the x-axis.
f(x)<0		The outputs of f(x) are negative or the graph of f(x) is below the x-axis.
f(x)>g(x)		The graph of f(x) is above the graph of g(x) or the outputs of f(x) are greater than the outputs of g(x).
f(x)=g(x)		The graphs of f(x) and g(x) intersect or the outputs are the same.

Required

You have two sets of cards, A cards and B cards.
Each A card gives you a representation of a function.
Select a B card and read each description.
Find an A card that matches all 5 statements on the B card and be ready to justify each statement.
Record the matches.
Proceed until all the A and B cards are matched. Be sure that you can justify all 5 statements on the B card with the function that you match it with.
