Question

How to find domain and range on a graph

Answer 1

Answer:

Please Find the answer below

Step-by-step explanation:

Domain : It these to values of x , for which we have some value of y on the graph. Hence in order to determine the Domain from the graph, we have to determine , if there is any value / values for which we do not have any y coordinate. If there are some, then we delete them from the set of Real numbers and that would be our Domain.

Range :  It these to values of y , which are as mapped to some value of x in the graph. Hence in order to determine the Range  from the graph, we have to determine , if there is any value / values on y axis for which we do not have any x coordinate mapped to it. If there are some, then we delete them from the set of Real numbers and that would be our Range .
