A point moves along the curve

12y = {x^3}

in such a way that the rate of increase of its ordinate is more than the rate of increase of abscissa. The abscissa of the point lies in the interval

View answer and explanation

Correct option: B

\left( { - \infty ,\; - 2} \right) \cup \left( {2,\;\infty } \right)

Option B (

\left( { - \infty ,\; - 2} \right) \cup \left( {2,\;\infty } \right)

) is correct because it represents the interval where the rate of increase of the ordinate is greater than the rate of increase of the abscissa.
