Question 1123926: Describe the end behavior of the polynomial function using lim f(x) and lim f(x)
x->oo x->-oo
f(x)=7x^2+x^3+2x-4
Please tell if the leading coefficient is less than or greater than 0
Also please tell what n equals and what the different lim f(x)'s equal
The x->oo and x->-oo correspond to the lim f(x)'s
Thank you so much!!

Same as x^3+7x^2+2x-4.
Lead coefficient is 1 and degree of f is 3. Cubic function.

f goes toward negative infinity to the extreme left and to the extreme right.
