Question

Graph ​ g(x)=2cosx ​.

Answer 1

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 = $\frac{2\pi }{B}$, c = phase shift, d = vertical shift

We know a = 2, B = $\frac{2\pi }{1}$, c = 0, d = 0.
