a.
To find: the domain of f.
a.

Answer to Problem 70RE
The domain is
Explanation of Solution
Given information: Let
Calculation:
The graph of the function , using graphing utility is shown below.
As the graph shows, as does any graph of a multiple of cos(x), the x-values (domain) decrease infinitely and increase infinitely. Around the infinities are parentheses, because the x-values never truly reach a set value. Therefore, the domain of function is
b.
To find: the range of f.
b.

Answer to Problem 70RE
The range is
Explanation of Solution
Given information:
Calculation:
As the graph shows, the minimum y-value is -2 and the maximum y-value is 4. Around those numbers are brackets because the graph does reach those values, rather than approach them.
Therefore, the range of function is
c.
To find: the period of f.
c.

Answer to Problem 70RE
The period of f is
Explanation of Solution
Given information:
Calculation:
The distance from the beginning of one period (0, -2) to the end of that period,
Therefore, the period of f is
d.
To find: is f an even function, odd function, or neither.
d.

Answer to Problem 70RE
Even.
Explanation of Solution
Given information:
Calculation:
A function is even if there is symmetry along the y-axis, as is the case with this graph.
Therefore, f is an even function.
e.
To find: all the zeros of f in
e.
