For this case we must find the domain and range of the following function:
By definition, the domain is given by all the values for which the function is defined. In this case, the given function is defined for all real numbers. That is to say:
Domain: (-∞,∞)
For its part, the range is the set of values that correspond to the domain. The values that the "y" variable takes. For this function, the range is given by all real numbers.
Domain is the values that x can take. In terms of real numbers x can take any value and the function will make sense. Since this is linear function the range is not limited too. So the range and domain coincide and are (-infinity;infinity)
