Question

Determine the end behavior for the function f(x)=-2x^3-8x

Answer 1

Hello @Haven55,

How are you doing? When you are finding the End Behavior, you need to find the degree and the leading coefficient. In this case, your lovely answer would be: Rises to the left and falls to the right.

I hope I helped, and contact me if you need more assistance.

Thank you,
Darian D.

Answer 2

The leading coefficient here is negative and the exponent is odd so the end behavior will be

as x→−∞,f(x)→−∞

​as x→∞,f(x)→∞
