Gotta trust my calculator

what an odd calculator. everyone in my class (adv. algebra 2) has either a TI-83 or a TI-84. it looks so... small compared to the glorious TI graphing calculators

But usually if it is an undefined answer, its fine to write undefeined ... If you can prove why it would undefined like maybe its an unreal answer ...

Ya you obviously haven't been in a higher level math where that can actually be an answer
