On the first one " The function is a reflection of its parent function over the x axis".....I'm not sure why this matters

But, anyway

We have the form

y = Asin (Bx) + D

A = the amplitude = 3

B = 2pi / period = 2pi / 4pi = 1/2

D = the shift up = 2

So....the function is :

y = 3 sin [ (1/2)x] + 2
