Answer to Problem 53RE
The function
Explanation of Solution
Given:
Concept used:
Modulus function make the graph shifted in the region of positive.
Its
Calculation:
Thee graph of the
Graphing device use here is Desmos graphing calculator. from the graph modulus symbolize the positivity of the function which is shown in the graph.
Through graph range can determined which is
Hence the function is even function.
(b)
To find:whether the Function is periodic if then described it.
(b)

Answer to Problem 53RE
The period here is
Explanation of Solution
Given:
Concept used:
Period is measured as distance it takes for the entire graph to repeat.
Since the period of the Cosine function is
Calculation:
Form the graph its clearly verified the periods as:
Form its range:
Hence the period here is
(c)
To find: The graph whether the function is even or odd.
(c)

Answer to Problem 53RE
The given function is even.
Explanation of Solution
Given:
Concept used:
Calculation:
Since the
It looks like infinitely many arches of length
Hence the given function is even.
