Question

In Maxima and Minima of functions of two variables, rt - 52> 0 and - r> 0 then f(x) has a. Maximum ob. Further investigations required O c. Minimum od Neither Maximum nor Minimum​

Answer 1

Step-by-step explanation:

For a function of one variable, f(x), we find the local maxima/minima by differenti- ation. Maxima/minima occur when f (x) = 0. x = a is a maximum if f (a) = 0 and f (a) < 0; • x = a is a minimum if f (a) = 0 and f (a) > 0; A point where f (a) = 0 and f (a) = 0 is called a point of inflection.
