f(x) = 2x
I need to determine the domain and range for f(x). I know that the domain is not equal to 5, but I'm not sure on how to find the range. I think it is all real numbers.
From this one problem, I have to also find the inverse. I came up with:
f(x) = -25x-2
But I don't think it is right.
Any help would be great thanks!
