Instructions
• Answer all questions in the spaces provided.
• Write your responses in English.
• In questions where a numerical answer is required, an exact value must be given unless otherwise specified.
• In questions where more than one mark is available, appropriate working must be shown.

Let \( f : \mathbb{R} \rightarrow \mathbb{R}, f(x) = x^2 - 4 \) and \( g : \mathbb{R} \rightarrow \mathbb{R}, g(x) = 4(x-1)^2 - 4 \).
a. The graphs of \(f\) and \(g\) have a common horizontal axis intercept at \((2, 0)\).
Find the coordinates of the other horizontal axis intercept of the graph of \(g\). 2 marks
b. Let the graph of \(h\) be a transformation of the graph of \(f\) where the transformations have been applied in the following order:
- • dilation by a factor of \( \frac{1}{2} \) from the vertical axis (parallel to the horizontal axis)
- • translation by two units to the right (in the direction of the positive horizontal axis)
