Domain $\mathbb{R}$, range the set of reals $\geq k$ where $k$ is a given constant.
Domain = $\{ x \mid x \in \mathbb{R} \}$. How would I write the range?

They have already told you the domain and range. If you're used to seeing the range in set builder notation, it is: $$ \{y \in \Bbb R \mid y \geq k\} $$
Hint: To come up with a function that has this domain and range, consider a parabola.

would that be given the formula for a function given that domain and range? – Maximiliano Sep 12 '13 at 05:28

1Yes. You are asked to come up with a function (there is more than one answer) that has the given domain and range. – Adriano Sep 12 '13 at 05:46
