- Determine the right-hand and left-hand behavior of the graph of
f(x).
Answer: The graph of f(x) approaches
on the left and 
on the right.
- If -5 and 5 are zeros of f(x), and if f(-2)=12, f(0)=-18,and
f(2)=50, how many real zeros does the function f(x) have?
Answer: The function has at least four distinct real zeros. If counted according to multiplicity, the function has five real roots (x=5 might be a double root).
Answer: The horizontal asymptote is y=0, and the vertical
asymptotes are x=6, and x=0.
