Homework Statement



Given the function, state the domain and range. I just want to make sure my notation is correct? More specifically, the im f, can you have the independent variable in there?

Your image is just barely legible. Instead of drawing a crude sketch of the problem, and then uploading an image of it, why not just type the problem in here?

For your problem, the domain is fine, but the range is not. All you have done is just restate the equation of the function. If the domain is the set of integers, what set do you get for the range? It might be helpful to check a few pairs of numbers.
