(a)
Answer to Problem 44E
The real zeros are
Explanation of Solution
Given information:
Consider
Calculation:
Find the zero’s of the given function
The function
Hence, the real zeros are
(b)
To find: whether the multiplicity of the each zero of the given function is even or odd .
(b)
Answer to Problem 44E
Multiplicity of
Multiplicity of
Explanation of Solution
Given information:
Consider
Calculation:
From part a,
The real zeros are
Multiplicity of
Multiplicity of
Hence, Multiplicity of
Multiplicity of
(c)
To find: the maximum possible number of turning points of the given function.
(c)
Answer to Problem 44E
The maximum number of turning points
Explanation of Solution
Given information:
Consider
Calculation:
The maximum number of turning points is one less than the degree of the function
Degree of the function is
Hence, the maximum number of turning points
(d)
To plot: the given function and to verify the results of previous parts.
(d)
Explanation of Solution
Given information:
Consider
Graph:
The graph of the
From the above graph, the maximum number of turning points
Hence, the results of previous parts are correct from the graph except maximum number
of turning points.
