Point of inflexion -

If at  x = a  the shape of the curve changes from concave to convex from convex to concave then at  x = a is known as the point of inflexion and 

f''(x)=0\:\;\:\:\:at\:\:x=a

-

 

 In (A), concavity remains downward in left and right both of 'a'

 In (B), concavity changes from downward to upward about 'a'

 In (C), concavity remains downward about 'a'

 In (D), concavity remains upwards about  'a'
