Question 12

A curve has equation y=f(x)y = f(x)y=f(x).

It is given that f′(a)=0f'(a) = 0f′(a)=0 and f′′(a)<0f''(a) < 0f′′(a)<0.

Identify the nature of the stationary point of the curve at x=ax = ax=a.

Tick one box.

A

A minimum point

B

A maximum point

C

A point of inflection

D

The nature cannot be determined
