If \(y = \sqrt{ax-b}\) express x in terms of y, a and b

  • A \(x = \frac{y^2-b}{a}\)
  • B \(x = \frac{y+b}{a}\)
  • C \(x = \frac{y-b}{a}\)
  • D \(x = \frac{y^2 + b}{a}\)

The correct answer is D. \(x = \frac{y^2 + b}{a}\)

\(y = \sqrt{ax-b}\)

\(y^2 = ax-b\)

\(y^2 +b = ax\)

\(x = \frac{y^2 + b}{a}\)
