What is the domain and range of #y = x + 3 #?
Is there any value of
The answer to this is no, so the domain is the set of all real numbers
You will notice that the graph of
Therefore, the range is also the set of all real numbers
Just keep this in mind. When you're given a linear function, its domain and range are both the set of all real numbers (unless the problem tells you it isn't).
