wow ok hmm

anonymous · Answer

first of all, does it really say 
$$\large y=\frac{x^2}{(x^2-2)^{-\frac{1}{2}}}$$

anonymous · Answer

yes thats what its showing on my screen lol

anonymous · Answer

we should then rewrite it as 
$$y=x^2\sqrt{x^2-2}$$

anonymous · Answer

okay i gotcha so we rewrite then what?

anonymous · Answer

the domain of this beast is from $(-\infty,-\sqrt2)\cup (\sqrt2,\infty)$ because you can''t take the square root of a negative number

anonymous · Answer

on the first interval it is deceasing, on the second it is increasing
odd for an algebra course

anonymous · Answer

oh and it is always greater than or equal to zero
