For what values in the domain is the square root of a negative number undefined (in the real number system)? For what values in the domain is the logarithm of a non-positive number undefined?

Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a ... The domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates). Only ... Many problems will ask you to find the domain of a function. What does this mean?
