**Reiny**, Monday, November 15, 2010 at 5:42pmfor large ± numbers the first term , -x^6 ,

is the "dominating" term, the other terms become more and more insignifant.

try a large positive + number,

e.g. x = 100

-x^6 = -1000000000000

x = -100

-x^6 = -1000000000000

so what do you think happens at both ends?
