Determine the period, amplitude, and phase shift of[tex]f(x)=3cos2\left \{ x-\frac{\pi }{4}]+1[/tex]

b) List the five critical points for the first cycle. (3 marks)

Use this information to sketch the graph off(x) for two

complete cycles. Determine [tex]\frac{1}{4}[/tex] wave and starting point.

Clearly label the scale on both axes. (3 marks)
