from the graph of the function, state the domain, the range, and the intervals on which the function is increasing, decreasing, or constant. complete parts (a) and (b). (a) the domain is . (type your answer in interval notation.)
Answer
Explanation:
Step1: Identify domain concept
The domain of a function is the set of all possible x - values.
Step2: Analyze the graph for x - values
Looking at the graph, we see that the function exists for all real x - values. In interval notation, all real numbers are represented as $(-\infty,\infty)$.
Answer:
$(-\infty,\infty)$
