f'(x)=2cosx
let f'(x)=0 for maxima and minima
therefore, x=90, 90+180=270
f''(x)=-2sinx
putting the value of x,
f''(x)=-2(1)= -2
f''(x)<0
therefore, it is maxima
f(x)=2sin(90)-1
=2-1=1
it has the value of maxima as 1
for x= 270,
f''(x)=-2(-1)=+2
therefore, it is minima(f''(x)>0)
f(x)=2sin(270) - 1= -2-1=-3
it has a minima value as -3

1, and -3.
f(x)=2sin90-1=2*1-1=2-1=1
f(x)=2sin270-1=2*-1-1=-2-1=-3
or you could use the sine curve.
f(x)=(amplitude)sin[(frequency)x]+vertical shift
amplitude is 2
vertical shift is -1
making the maximum 2-1, or 1, and the minimum -2-1, or -3. =)

Sorry, pal... I come here when I'm drunk, and I don't feel like doing math right now.

You Are the lazy one.
The answer is ...
Max(X) is 1
Min(X) is -3
