SOLUTION

TO CHOOSE THE CORRECT OPTION

A point at which function is neither minimum nor maximum is called as a -

A. stationary point

B. minimum point

C. maximum point

D. saddle point

EVALUATION

A function f(x, y) is said to have maximum or minimum at x = a, y = b according as

f(a+h, b+k) < or > f(a, b)

for all positive or negative small values of h & k

A point where maximum value or minimum value occurs is called stationary point

A point where f(x, y) neither have maximum nor have minimum value is called saddle point

Hence the correct option is D. Saddle Point
