Since you can plug in any number in for x, this means the domain is all real numbers. Consequently, since any number can go in, any number can come out. So the range is all real numbers.


Notice if we graph f%28x%29=3x%2B2 we can see that the domain and range is all real numbers.

+graph%28+500%2C+500%2C+-10%2C+10%2C+-10%2C+10%2C++3x%2B2%29+
