What is the end behavior of a fourth degree polynomial with a negative 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 negative.

• 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 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.

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