TypeFind derivative of polynomial
  1. Given
$$y = 3 \sqrt { x } - 6 x + 4 , \quad x > 0$$
  1. find \(\int y \mathrm {~d} x\), simplifying each term.
    1. Find \(\frac { \mathrm { d } y } { \mathrm {~d} x }\)
    2. Hence find the value of \(x\) such that \(\frac { \mathrm { d } y } { \mathrm {~d} x } = 0\)
