Answer:
The range of the given function is the set of real numbers.
Step-by-step explanation:
Function: It is defined as mapping between two non empty set A and B in which each element of set A is mapped to one element of set B.
Domain: It is define as the set of elements of set A which is substitute in place of x in the given function.
Range: It is define the set of elements which are obtained after assigning values of x in the given function.Range is a subset of codomain or equal to codomain.
In given figure
We can see the graph of line is passing through positive and negative values of y-axis.
The range of given function includes 2,-2,-3,-4,....
Therefore, the range of given graph is the set of real numbers.
