It's easy my friend
To find the extrema you have to find the derivative

x2 + 2's derivative is 2x, now what's the biggest possible value of 2x, well that's infinity, so infinity is your extrema, and how is it graphed? Well it should look like a curvy ramp that goes to infinity

The maximum value of sin(x) is 0.999... if anyone tells you otherwise, even your teacher, fucking eviscerate them.
For the second bit, it's concave down when it looks like a titty pointing upwards, and it's concave up when the titty looks like a 90 year old granny's.

f(x) = sin x
f '(x) = cos x
f "(x) = -sin x

to find extreme:
f '(x) = 0 => cos x = 0 => x = +- pi/2 + 2pi.n
for 0 < x < 2pi : x = pi/2 and x = 3pi/2

to see if it's max or min:
f "(pi/2) = - sin pi/2 = -1 , -1 < 0 => pi/2 is max
f "(3pi/2) = -sin 3pi/x = 1 , 1 > 0 => 3pi/2 is min
