18 The graph of \(y = \mathrm{f}(x)\) is shown on the grid below.

Grid with x from -4 to 6 and y from -3 to 3 showing the curve y = f(x), a U-shaped curve through (0, 0) and (2, 0) with minimum point (1, -1)
(a) On the grid above, sketch the graph of \(y = \mathrm{f}(x - 2)\) (1)
Grid with x from -5 to 5 and y from -3 to 3 showing graph A on the left and graph B on the right; graph B is the reflection of graph A in the y-axis

On the grid, graph A has been reflected to give graph B.

The equation of graph A is \(y = \mathrm{g}(x)\)

(b) Write down the equation of graph B. (1)
