For the function

f(x,y)=x^3+y^3-3xy-ln(r)-e^c+t

You find that at the point (2,4) the value of the function is 50

f(2,4)=50

Suppose you were to estimate the values of the following points:

A = (1.997,4.003)

B = (2.004,3.996)

C = (2.000,3.997)

D = (1.996,4.000)

At which point(s),would you expect (without calculation) the value of the function be larger than f (2,4) = 50? Also provide a quick (one line) explanation of why you would expect the value to be larger than 50.
