f(x)->_________ as x->-infinity

f(x)->_________ as x->infinity

In the blanks, I say for the first one infinity then -infinity for the second one.

**Reiny**, Thursday, September 11, 2008 at 1:00pmuse an intuitive approach.

as x becomes "very large" your numerator is dominated by the 3x^2 term and your denominator is dominated by the 2x^2 term, the other terms become less and less significant as x gets bigger

so your function approaches f(x) = 3x^2/2x^2 = 3/2

so the limit is 3/2
