Easy -1.8 This is a straightforward graph recognition question requiring only basic knowledge that cos(½x) has period 720° and starts at y=1 when x=0. It's a single-mark multiple choice question with no calculation or problem-solving required—purely visual pattern matching of a standard transformation.
The graph of the function \(y = \cos \frac{1}{2}x\) for \(0° \leq x \leq 360°\) is one of the graphs shown below.
Identify the correct graph.
