Which polynomial function could be represented by the graph below?

f(x) = x3 + x2 – 6x
f(x) = x3 – x2 – 6x
f(x) = –2x3 – 2x2 + 12x
f(x) = –2x3 + 2x2 + 12x
will mark brainliest for correct answer

Note that

1.

The x-intercepts are at points x=-3, x=0, x=2. The graph should be increasing - decreasing - increasing.

2.

The x-intercepts are at points x=-2, x=0, x=3. The graph should be increasing - decreasing - increasing.

3.

The x-intercepts are at points x=-3, x=0, x=2. The graph should be decreasing - increasing - decreasing.

4.

The x-intercepts are at points x=-2, x=0, x=3. The graph should be decreasing - increasing - decreasing.

From the diagram you can see that x-intercepts are at points x=-3, x=0, x=2 and the graph is   decreasing-increasing-decreasing.

correct choice is 3.
