Eliminating a and b from the relation y = a log x + b , we get ________

Options

  1. Ax y 2 + y 1 = 0
  2. Bx y - y 2 = 0
  3. Cx y 1 + y 2 = 0
  4. Dy 2 y 2 + x = 0

Correct answer

A. x y 2 + y 1 = 0

Step-by-step solution

y = a log x + b Differentiate ⇒ y 1 = a x + 0 ⇒ x y 1 = a Differentiate ⇒ y 1 + x y 2 = 0
