10 cards from this deck
A point where the graph changes concavity (concave up ↔ concave down)
f′′(x)f''(x)f′′(x) changes sign at x=cx = cx=c
f′′(x)<0f''(x) < 0f′′(x)<0
f′′(x)>0f''(x) > 0f′′(x)>0
Find second derivative f′′(x)f''(x)f′′(x)
If f′′(x)f''(x)f′′(x) changes sign around that point
No, must check for sign change in f′′(x)f''(x)f′′(x)
(0,0)(0, 0)(0,0)
No, f′′(x)f''(x)f′′(x) doesn't change sign
Check sign of f′′(x)f''(x)f′′(x) before and after the point
