Plug in all of the numbers of the domain (the domain are just x values) and then you will find the range. The range is just the smallest to largest y value.

anonymous · Answer

I did, my answers didnt show up

amistre64 · Answer

the range is all the y values that the domain produces, not an interval.  the domain is discrete, the range is discrete

anonymous · Answer

When i plugged in -3 for the equation i ended up with the y value of -2.5 
It doesn't show that on the answers!

anonymous · Answer

Yeah, what he ^ said. I'm not familiar with whatever notation that is though. I've never written a range like that.

simplify:  3 - 6/x

when x=-3,  3--3 = 0

Ohhhh, okay. I was using a calculator and the equation was messed up. Ugh, i really need to start doing things by hand. :/
