2．（a）On separate diagrams，sketch the curves with the following equations．On each sketch you should label the exact coordinates of the points where the curve meets the coordinate axes．
（i）\(y = 8 + 2 x - x ^ { 2 }\)
（ii）\(y = 8 + 2 | x | - x ^ { 2 }\)
（iii）\(y = 8 + x + | x | - x ^ { 2 }\)
（b）Find the values of \(x\) for which $$\left| 8 + x + | x | - x ^ { 2 } \right| = 8 + 2 | x | - x ^ { 2 }$$
