Twice Differentiable function ?

Update:

Based on the graph above when x=0 the graph of f has (choose one: a relative min, a relative max, a non extreme horizontal tangent, no horizontal tangent line) and (choose one: an inflection point, no inflection point)

Update 2:

#2: We can also infer that f' when x =0 is (choose one: positive, negative, zero (pos to neg), zero (neg to pos), zero (no sign change)) and has (choose one: a relative min, a relative max, no relative extreme).

#3 Furthermore, we can state that f'' is (choose one: positive, negative, zero (neg to pos), zero (no sign change)) when x=0.

Update 3:

 

Update 4:

    Your photograph is so terrible that it's really hard to tell, but it looks like the graph has a relative minimum at x = 0, and no inflection point there.
