Question

Determin the end behavior for:4x^3-5x^2-7x+2

Answer 1

If I'm interpreting right, the end behavior you are referring is essentially when x->infinity?

If so, polynomials will follow the trend of the leading exponent's term. In this case, it is 4x^3. As x approaches infinity, 4x^3 goes to positive infinity so therefore so does the polynomial.

Answer 2

thank you :)

Answer 3

Since 4x^3 has coef 4 is positive => both ends rise up!

Answer 4

thank you
