how do i find domain and range of functions on a graph which does not have any numbers or anything marked on it?
it's kinda hard to explain without a picture (i'll see if i can upload one) but does anyone know a general way to figure it out?

The domain is the projection onto the x-axis, the range is the projection onto the y-axis.

A function is a relation in which each x value is paired with exactly one y value.
Domain of a relation is the set of all first coordinates or x coordinates
Range of a relation is the set of all second coordinates or y coordinates
{(-1, 3)(1, 4) (3, 7)}
Domain:{ -1, 1, 3 }
Range: { 3, 4, 7 }

I've been taking this kind of math since I was 14... That's 6 years and i've never completely understood calculus. ARGH! GOOD LUCK. GO TO... www.cramster.com
Go to Cramster answer board. Ask your math questions there. Someone will answer pretty quickly. It's the best thing that ever happened to me. You may have to sign up for free account, but it's worth the A.
