what are the domain and range of the step function below?\no domain = {all real numbers}, range = {all real numbers}\no domain = {all real numbers}, range = {... - 4, - 1, 2, 5, ...}\no domain = {... - 5, - 2, 1, 4, ...}, range = {... - 4, - 1, 2, 5, ...}\no domain = {all integers}, range = {all real numbers}
Answer
Explanation:
Step1: Identify domain from graph
The graph extends horizontally without breaks. So, the domain includes all real - x values. Domain is all real numbers.
Step2: Identify range from graph
The function takes on only the y - values of - 4, - 1, 2, 5, etc. These are discrete values. Range is the set of values {..., - 4, - 1, 2, 5,...}.
Answer:
domain = {all real numbers}, range = {..., - 4, - 1, 2, 5,...}
