Answer:
Domain is set of all real numbers
Range is set of all real numbers
Explanation:
Domain is the set of x values for which the function is defined
to find domain we look at the graph and check if there is any restriction for x
WE have line graph for all x values
So there is no restriction for x. Hence, Domain is set of all real numbers
Range is the set of y values for which the function is defined
to find range we check the continuity on graph
The graph is contininious and there is no break . The graph is continious for all y values
So range is set of all real numbers
