Supposeh(x)is a polynomial function that satisfies

h (x)< 0 for x (,3)(1,1)

h(x) > 0 for x (3,1)(1,)

Choose the statements that best describe the graph ofh.

1. The functionhhas critical values atx=3,x=1, andx=1
2. The functionhhas inflection points within the intervals(3,1) and(1,1)
3. The functionhis concave down on the interval(,3)(1,1) and concave up on the interval(3,1)(1,)
4. The functionhhas inflection points atx=3,x=1, andx=1
5. The functionhis decreasing on the interval(,3)(1,1) and increasing on the interval(3,1)(1,)
