Find the limit: lim x->0 (3/x^2 - 2/x^4)
The Attempt at a Solution
I've tried manipulating it in a lot of ways, but nomatter what I do I've still either got the limit of the denominator = 0 or one of the terms in either the num. or den. being divided by x (which is tending to zero)
I've got as far as lim x->0 ( 9x^4 - 4 / 3x^6 + 2x^4 ) but this doesn't help as the den. = 0.
I've graphed this function and had a look - the limit should equal -(infinity).
