Determine the DOMAIN and RANGE from the graph

Given:

The graph of a function.

To find:

The domain and range of the function.

Solution:

We have, the graph of a function and we need to find the domain and range of the function.

We know that, domain is the set of input values (x-values) and range is the set of output values (y-values).

From the given graph it is clear that function is defined for all values of x except x=0 because as x tends to 0 the function tends to negative or positive infinite. So, domain can be any real number except 0.

From the given graph it is clear that the value of function can be any real number except y=0. So, range can be any real number except 0.

Therefore, the correct option is B.

to determine the unit cost your would divide the total cost by the number sold.
