The diagram shows graphs with equations \(y = f(x)\) and \(y = g(x)\).
Describe fully a sequence of two transformations which transforms the graph of \(y = f(x)\) to \(y = g(x)\).
Solution
To transform \(y = f(x)\) to \(y = g(x)\), we perform the following transformations:
1. Stretch the graph of \(y = f(x)\) by a factor of 2 in the y-direction. This means that every y-coordinate of the graph is multiplied by 2.
2. Translate the resulting graph by \(\begin{pmatrix} -6 \\ 0 \end{pmatrix}\), which means shifting the graph 6 units to the left.
These transformations can be applied in either order to achieve the same result.
