2 A curve has equation \(y = x ^ { 4 } + x\).
- Find the gradient of the line passing through the point \(( - 2,14 )\) and the point on the curve for which \(x = - 2 + h\). Give your answer in the form
$$p + q h + r h ^ { 2 } + h ^ { 3 }$$
where \(p , q\) and \(r\) are integers.
- Show how the answer to part (a) can be used to find the gradient of the curve at the point ( \(- 2,14\) ). State the value of this gradient.
