15. The following diagram shows a sketch of the curve \(y = f(x)\).

In each of the following questions, the graph of \(y = f(x)\) has been transformed.

Circle the only possible equation of the transformed curve. [1]
\(y = f(x) - 3\) \(y = f(x - 3)\) \(y = \tfrac{1}{3} f(x)\) \(y = f(x + 3)\) \(y = f(x) + 3\)

Circle the only possible equation of the transformed curve. [1]
\(y = f(x) - 6\) \(y = -f(x)\) \(y = f(x + 8)\) \(y = f(x) + 6\) \(y = f(-x)\)

Circle the only possible equation of the transformed curve. [1]
\(y = f(x) + 10\) \(y = f(x + 10)\) \(y = -4f(x)\) \(y = f(x - 10)\) \(y = f(x) - 10\)
