CONCAVITY AP Calculus AB, please help. where necessary to graph just need to explain, or maybe draw out for help. Thanks

1) Below is a chart that gives some information regarding a twice-differentiable function f(x).(n/a = "not applicable")

x<-4 x=-4 -4<x<0 x=0 0<x<4 x=4 4<x

f(x) n/a -3 n/a 1 n/a 5 n/a

f"(x) negative 0 positive 0 negative 0 positive

Concavity ? n/a ? n/a ? n/a ?

Fill in last row of chart (4 ?'s) with proper concavity (concave up or down) and then sketch a graph that satisfies all the conditions in the chart.
