Step-by-step explanation:

To graph the function, let's find the values of f(x) for some values of x.

If x = 0

f(x) = cos(2x) + 1

f(0) = cos(2(0)) + 1

f(0) = cos(0) + 1

f(0) = 1 + 1 = 2

If x = π/2

f(π/2) = cos(2(π/2)) + 1

f(π/2) = cos(π) + 1

f(π/2) = -1 + 1 = 0

If x = π

f(π) = cos(2π) + 1

f(π) = 1 + 1

f(π) = 2

Answer:

So, using the points (0, 2), (π/2, 0) and (π, 2), and following the form of a cosine function, we get that the graph is
