TopicFunction Transformations
TypeTransformation of specific function type
DifficultyModerate -0.8 This is a straightforward application of horizontal translation to a standard logarithmic function. Students need only recall that f(x-4) shifts the graph 4 units right, find the x-intercept by solving ln(x-4)=0, and identify the vertical asymptote. It requires basic knowledge of function transformations and properties of ln(x), but involves no problem-solving or novel insight—purely routine application of well-practiced techniques.

2. Given that $$f ( x ) = \ln x , x > 0$$ Sketch on separate axes the graphs of
i) \(y = f ( x )\) ii) \(\quad y = f ( x - 4 )\) Show on each diagram, the point where the graph meets or crosses the \(x\)-axis. In each case, state the equation of the asymptote.
