(B) not continuous (A) continuous (D) None of these (C) differentiable 3 If f (x, y) is differentiable function, then: (A) only f exists (B) both fy and y exist (C) only fy exists (D) neither f, nor fy exists 4 The first term in the Taylor's series expansion of f(a + h,b + k) about the point (a,b) is . (A) -f(a, b) (B) f(a+h, b) (C) fa,b +k) (D) f(a,b) and S1,2) =f, (1,2) = 0, Sr (1,2)= 6 5. Given that Ja (1,2) Jy (1,2) -S5 (1,2) = 72.
