Question 78551: Determine thed omain of domain
From what I learned in class I assumed I was supposed to use scientific division to find all possible zeros but I have no idea what numbers I would plug into that equation.
My deepest thanks for any help you can give, you're all life savers! :] Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Determine thed omain of
===========
You only need to look at the denominator; Since it is a radical the radicand
must be >=0; but since it is the denominator it cannot be zero.
So it must be 2x^3+7x^2+6x-21>0
Graph to see where it is >0
I get x>1.2083653
That is the domain
