Question

using the given graph of the function f, find the following.
(a) the intercepts, if any
(b) its domain and range
(c) the intervals on which it is increasing, decreasing, or constant
(d) whether it is even, odd, or neither
(a) what are the intercepts?
$(-\pi,0),(0,0),(\pi,0)$
(simplify your answer. type an ordered pair. use a comma to separate answers as needed. type an exact answer, using $\pi$ as needed.)
(b) the domain is $-\pi,\pi$
(type your answer in interval notation. type an exact answer, using $\pi$ as needed.)
the range is $\square$
(type your answer in interval notation. type an exact answer, using $\pi$ as needed.)

Explanation:

Step1: Determine the range

The range of a function is the set of all possible \(y -\)values.
Looking at the graph, the minimum \(y -\)value is \(-4\) and the maximum \(y -\)value is \(4\).

Answer:

\([-4,4]\)
