y = asinbx +c
If you substitute 0 in place of x then answer will be y = 0 +3
so c = 3
y= asinbx + 3
b is the frequency, i.e. the no of waves or cycles in the interval given (0 ≤ x ≤ 2p.)
since there are 2 waves so b = 2
a is the amplitude, i.e., the difference between maximum value to the starting point
so you could either obtain value of a by 9-3 = 6
or 3+3 = 6
y = 6sin2x + 3
