2 The equation of a curve is \(y = 4 \sqrt { } x + \frac { 2 } { \sqrt { } x }\).
- Obtain an expression for \(\frac { \mathrm { d } y } { \mathrm {~d} x }\).
- A point is moving along the curve in such a way that the \(x\)-coordinate is increasing at a constant rate of 0.12 units per second. Find the rate of change of the \(y\)-coordinate when \(x = 4\).
