What is the stationary point for the curve

 $y=x^2-4$  

• A minimum at ( 0, -4)

• A maximum at (0, -4)

• A minimum at (0,4)

• A maximum at (0,4)

 What is the stationary points for the curve

 $y=x^3+3x^2-24x$  and determine their nature.

• Maximum point : (2, -28) and minimum point : (-4, 80)

• Minimum point : (2, 28) and maximum point : (-4, 80)

• Minimum point : (2, -28) and maximum point : (4, 80)

• Minimum point : (2, -28) and maximum point : (-4, 80)

Extremum points are either

• local maximum

• fixed point

• inflection point

• local minimum

Local maximum point is obtained when

• $f'\left(x\right)$ exchange from negative to positive
  

• $f''\left(x\right)$ exchange from positive to negative

• $f'\left(x\right)$ exchange from positive to negative

• $f''\left(x\right)$ exchange from negative to positive

Local minimum point is obtained when

• $f'\left(x\right)$ exchange from negative to positive

• $f''\left(x\right)$ exchange from positive to negative

• $f'\left(x\right)$ exchange from positive to negative

• $f''\left(x\right)$ exchange from negative to positive
