@teresatripp Nope.

Whoops, I copied the wrong link, here's the correct one: http://www.wolframalpha.com/input/?i=4x2+%2B+4y2+%3D+64

@aajugdar Don't tell me you've never been there ;)

The domain means all values of x the function f(x) (although this equation is technically not a function) can accept. In this case, you will notice that the domain is between -4 and 4 - it can't get any smaller or larger. In this case, we write the domain as \(-4 \leq x \leq 4\).

The range means all values of y this (not-)function can generate (what's the right verb?). In this case, you notice that the range is also between -4 and 4. You should know how to write this one ;)
