Again, we will work backward -
We will study a graph (rather than a function)
to determine the function (rather than what the graph might look like).
Below is a graph with some highlighted key points,
so we will begin by analyzing the graph to determine:
~ Zeros of the function
~ Factors of the function
~ Vertical asymptote (if any)
~ Negative and positive regions
~ The rational function
~ The number line with the zeros and +/- regions
~ The rational inequality
~ Solution Set
Example 10: Graphically
Let's assume the green area contains the solution set.
We will now analyze the graph to answer the questions noted above.
