step 2 of 2: determine the domain and range of the graph. express your answer in interval notation.
Answer
Explanation:
Step1: Identify domain
The graph extends horizontally from negative - infinity to positive infinity. So the domain is all real numbers. $(-\infty,\infty)$
Step2: Identify range
The highest point of the graph on the y - axis is at some positive y - value and it extends downwards to negative infinity. The maximum value of y seems to be around 2 (by visual inspection). So the range is $(-\infty, 2]$.
Answer:
Domain: $(-\infty,\infty)$ Range: $(-\infty, 2]$
