Jake Huether Posted January 15, 2004 Share Posted January 15, 2004 Sorry for popping my head in too late. Heres a cool site that explaines the range vs. domain a little better. I'm a mechanical engineer. If you have math questions just let me know. That is if Deeds doesn't answer you first. ;) Link to comment Share on other sites More sharing options...

Jake Huether Posted January 15, 2004 Share Posted January 15, 2004 h(x)=2(x-7)(x+5) Without giving you the direct answers. Domain is the span of values for x in this particular function (-2 to 5 for example, those aren't the answers). Range is the values of y in this particular funcition (-10 to infinity for example). The big picutre, once this thing is graphed, will show you the range and domain. Zero's are where the function h(x) = zero. That one's easy. As you know, anything times zero is zero. So only one () on the right side has to be zero for h(x) to be zero. x=7 for example. 2(7-7)(7+5) = h(x). Since 7-7 = 0, then h(x) = 0. Same with x=-5. hope that helped.
