Question

What are the domain and range of the function ? domain: all real numbers range: all real numbers greater than or equal to –5 domain: all real numbers range: all real numbers greater than or equal to –4 domain: all real numbers between –2.5 and 2.5 range: all real numbers domain: all real numbers between –2.5 and 2.5 range: all real numbers greater than or equal to –5

Answer 1

a

Explanation:

Answer 2

Option A Domain: all real numbers between –2.5 and 2.5 range: all real numbers greater than or equal to –5

Explanation:

Domain corresponds to the values of x and Range corresponds to the value of y. If sketch the graph on an online calculator we can see that the domain lies between -2.5 and 2.5 for x and the range corresponds to y as in this case

range ≥ -5.
