Question

Describe the end behavior using limits for the polynomial: 7x^2 - x^3 + 3x -4

Answer 1

if you take the limit as x approaches negative infinity, you'll find that y approaches infinity.
if you take the limit as x approaches infinity, you'll find that y approaches negative infinity.

what's is the end behaviour?

Answer 2

How is y approaching infinity as x approaches neg. infinity? My notes say if the lead term is positive and highest power is odd, as x approaches infinity y approaches infinity and as x approaches neg. infinity, y approaches neg. infinity

Answer 3

your lead term is negative, not positive.

Answer 4

i thought 7 has to be the lead term because it is the coefficient?

Answer 5

x^2 is not the highest degree in your polynomial

Answer 6

ok i understand thank you so much!
