Question

part 1 of 10
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.)

Explanation:

Step1: Analyze the graph (a)

The graph (a) is a line that extends infinitely in both the left and right directions (since there are no breaks or endpoints shown, and the arrows indicate it continues). For a function, the domain is all the x - values for which the function is defined. Since this line goes from negative infinity to positive infinity on the x - axis, the domain includes all real numbers.

Step2: Write in interval notation

In interval notation, all real numbers are represented as $(-\infty, \infty)$.

Answer:

$(-\infty, \infty)$
