To graph: The rational function
Explanation of Solution
Given information:
The rational function
Graph:
Step-1: The factors of
The function is
Therefore, domain of the rational function
Step-2:
Therefore,
That is,
Therefore,
Thus, the function
Step-4: As
The multiplicity of
Step-5: The degree of numerator is
Therefore, the horizontal asymptote of
To check whether graph of
That means, graph of
Step-6: The real zeroes of the numerator are
The intervals using the numbers
Step-7: The graph of
The graph of function
Graph of
The graph of
The graph of
The graph of
Therefore, the graph of rational function
Interpretation:
The graph represents rational function
