Question . 57
If x & y are real numbers, the functions are defined as f (x, y) = | x + y |,F (x, y) = –f (x, y) and G (x, y) = –F (x, y) . Now with the help of this information answer the following questions.
If y = x, which of the following will give x² as the final value ?
A : f (x, y) G (x, y)4B : G (f(x, y) f (x, y), F (x, y)/8C : –F (x, y) G (x, y)/log2 16D : –f (x, y) G (x, y) F (x, y)/F (3x, 3y)
