Answer:
Domain is all the real numbers
Step-by-step explanation:
Standard formula for the linear function is:
y = mx + b
The linear functions always continue infinitely in each direction.
Any real number can be x and get a value for the y axis. For any real number, there is always a value x that gives you a natural number in the output. Unless the linear function is constant, for example f(x) = 5, there is no restriction on the range,
The domain are all the real numbers
