The degree of the polynomial function f(x) is 4. The roots of the equation f(x)=0 are −2, −1, 1 and 3.

Which graph could be the graph of f(x)?

upper right

Step-by-step explanation:

In each case, the graph must cross the x-axis at the locations listed as roots (zeros) of the function (values of x where f(x)=0).

1. The zeros are given as -4, -1, 2, 5. Those x-values are where the curve must cross y=0 (the x-axis).

2. The zeros are given as -1, 0, 4. Those x-values are where the curve must cross y=0 (the x-axis).
