(a)
Answer to Problem 15CR
Solution:
The equation of the graph is
Explanation of Solution
Given information:
The polynomial function has degree
The
Factor theorem is
As
For real zero
The required polynomial function would be multiplication of all these three factors.
The required polynomial function would be
It is given that
Substitute
Divide both sides by
Reduce the fraction to the simplestform.
Substitute
Using distributive property,
Therefore, the required polynomial function is
To graph the given polynomial function, plot the
Therefore, the graph of the polynomial
(b)
The rational function from
(b)
Answer to Problem 15CR
Solution:

Explanation of Solution
Given information:
The rational function has
The
So, corresponding factors
As line
The required rational function would be
It is given that
Substitute
Divide both sides by
Reduce the fraction to the simplest form
Substitute
Using distributive property,
Therefore, the required rational function is
To graph the given rational function, plot the
Therefore, the graph of rational function
