7.3. Guide to graph rational functions (RF).
1) Determine the horizontal asymptote (HA) if any and the end behavior
of the function.
2) Determine the vertical asymptote (VA) if any and the domain of the
function.
3) Identify x and y intercept.
4) Evaluate additional points such as:
-Big negative and positive numbers.
-Between vertical asymptotes.
-Values near of vertical asymptote (at the left and right of VA)
-Big positive numbers.
5) When f(x) is increasing and decreasing.
6) Identify approximately the turning points.
7) When the function is f(x)>0 and when the function is f(x)<0
8) Specify the Range of the function.
9) Graph it.
