Hi

What will be the range of the function f(x) = 1-1/x .

1. The domain is given as [0, infinity)

2. The domain is given as [0, infinity]

I am primarily confused if "1" will be included or not? The limit of the function tends to 1 but it will never actually reach 1. So, will the range be [-infinity,1) or [-infinity,1] or (-infinity,1) or (-infinity,1]

thanks
