Critical

Step-by-step explanation:

please mark me as brainliest

Answer 2

◇ Required answer :-

a function for a surface that depends on two variables x and y. When we find the slope in the x direction (while keeping y fixed) we have found a partial derivative. Or we can find the slope in the y direction (while keeping x fixed).

So ur answer is :

c) Critical
