Figure 1 shows a sketch of the curve with equation \(y = \mathrm { f } ( x )\).
The curve passes through the origin \(O\) and the points \(A ( 5,4 )\) and \(B ( - 5 , - 4 )\).
In separate diagrams, sketch the graph with equation
- \(y = | f ( x ) |\),
- \(y = \mathrm { f } ( | x | )\),
- \(y = 2 f ( x + 1 )\).
On each sketch, show the coordinates of the points corresponding to \(A\) and \(B\).
