| Topic | Function Transformations |
| Type | Multiple choice transformation |
| Difficulty | Easy -1.2 This is a straightforward recall question about function transformations. Students need only remember that a stretch scale factor k parallel to the y-axis transforms y=f(x) to y=kf(x), then apply this to get y=2logâ‚„x. It's a single-step multiple choice question testing basic transformation rules with no problem-solving required. |

3 The curve
$$y = \log _ { 4 } x$$
is transformed by a stretch, scale factor 2 , parallel to the $y$-axis.\\
State the equation of the curve after it has been transformed.\\
Circle your answer.\\[0pt]
