What is the end behavior of a second degree polynomial with a positive leading coefficient?

As x gets larger and larger in the positive direction, f(x) gets more positive. As x gets larger and larger in the negative direction, f(x) gets more positive.

As x gets larger and larger in the negative direction, f(x) gets more negative. As x gets larger and larger in the negative direction, f(x) gets more positive.

As x gets larger and larger in the positive direction, f(x) gets more negative. As x gets larger and larger in the negative direction, f(x) gets more positive.

As x gets larger and larger in the positive direction, f(x) gets more positive. As x gets larger and larger in the negative direction, f(x) gets more negative.

Which factor has a multiplicity of 2 of (x + 2)(x - 1)(x + 3)(x - 2) 2 ? What does this tell you about the graph?

(x - 2), and it will make a parabola shape at the x-intercept.

(x + 2), and it will go straight through the x-intercept

(x - 1), and it will make a parabola shape at the x-intercept.

(x +3), and it will go straight through the x-intercept.

What is the end behavior of a third degree polynomial with a positive leading coefficient?

As x gets larger and larger in the positive direction, f(x) gets more positive. As x gets larger and larger in the negative direction, f(x) gets more negative.

As x gets larger and larger in the positive direction, f(x) gets more positive. As x gets larger and larger in the negative direction, f(x) gets more positive.

As x gets larger and larger in the negative direction, f(x) gets more negative. As x gets larger and larger in the negative direction, f(x) gets more positive.

As x gets larger and larger in the positive direction, f(x) gets more negative. As x gets larger and larger in the negative direction, f(x) gets more positive.

What is the end behavior of a fourth degree polynomial with a negative leading coefficient?

As x gets larger and larger in the negative direction, f(x) gets more negative. As x gets larger and larger in the negative direction, f(x) gets more negative.

As x gets larger and larger in the positive direction, f(x) gets more positive. As x gets larger and larger in the negative direction, f(x) gets more positive.

As x gets larger and larger in the positive direction, f(x) gets more negative. As x gets larger and larger in the negative direction, f(x) gets more positive.

As x gets larger and larger in the positive direction, f(x) gets more positive. As x gets larger and larger in the negative direction, f(x) gets more negative.

The end behavior of a polynomial function is determined by the degree and the sign of the leading coefficient. Identify the degree of the polynomial and the sign of the leading coefficient
