Question

For the polynomial f(x) =-2x^3 - 2x^2 + 7x - 25 as
x -> negitive infinity, f(x) -> infinity?

Is it true or false?

Answer 1

intuitively i would say yes because the largest term is -2x^3 and for high negative values of x we get a very high positive value of -2x^3

Answer 2

Great!! Thank you for your help!!!

Answer 3

-2x^3 has the highest degree of x

Answer 4

yes - it is correct - I've just graphed it on my calculator
