Given two functions are

f(x) = 2 cos(x)

g(x) = 3 sin(x+ \pi)

We know that the maximum value of cos x and sin x is always 1

y= maximum of cos = 1

y= maximum of sin =1

f(x) = 2 cos(x)

y= 2 (max of cos) = 2(1) = 2

g(x) = 3 sin(x+ \pi)

y= 3 (max of sin) = 3(1) = 3

g(x) = 3 sin(x+ \pi) has the maximum value.
