The graph touches at x=-3 and x=2. So we will have even powers on (x+3) and (x-2) and crosses at x=-1 and x=3. So we have odd powers on on (x+1) and (x-3). Which is true for all options.

and we see that f(0) is nearly equal to -12. Lets check all the options.

And we find that f(0)=-12 for only first option. So correct choice is A.
