10 A curve has gradient function
$$\frac { \mathrm { d } y } { \mathrm {~d} x } = 3 x ^ { 2 } - 12 x + c$$
The curve has a turning point at ( \(- 1,1\) )
10
- Find the coordinates of the other turning point of the curve.
Fully justify your answer.
10 - Find the set of values of \(x\) for which \(y\) is increasing.
