ANSWER

EXPLANATION

We know how to graph

[tex]f(x) = \cos(x) [/tex]

The given function

[tex]f(x) = \cos(2x) + 1[/tex]

is obtained by transforming the graph of

[tex]f(x) = \cos(x)[/tex]

The period is π.

Hence we graph cos(x) such that it completes one cycle after every π units and then shift this graph up by 1 unit to obtain

[tex]f(x) = \cos(2x) + 1[/tex]

The amplitude is 1.

Hence it's range is

0≤y≤2
