Answer:
we can draw the graph of cosine with amplitude 2.
Step-by-step explanation:
In the given function g(x) = 2cosx we know the following parameters which are helpful to draw the graph.
Its a cosine graph given in the form of y = acos(Bx + c) + d
Here a is amplitude, period = [tex]\frac{2\pi }{B}[/tex], c = phase shift, d = vertical shift
We know a = 2, B = [tex]\frac{2\pi }{1}[/tex], c = 0, d = 0.
