Question

What is the range of the function graphed below

Answer 1

For finding range pay attention to y axis you can see f(x) includes all numbers so  the range is R

Answer 2

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.
