उत्तर

If f(x) = `|(0, x - "a", x - "b"),(x + "b", 0, x - "c"),(x + "b", x + "c", 0)|`, then f(0) = 0.

Explanation:

f(x) = `|(0, x - "a", x - "b"),(x + "b", 0, x - "c"),(x + "b", x + "c", 0)|`

⇒ f(0) =`|(0, -"a", -"b"),("a", 0, -"c"),("b", "c", 0)|`

Which is skew-symmetric determinant of order 3

Hence f(0) = 0.
