The only variable on the right hand side is sin(x).
The maximum value of sin(x) is 1.
So, the max value of 3sin(x) is 3*1 = 3
and so, the max value of 3sin(x) + 2 is 3+2 = 5.

20 and the vertex of the parabola is at (3, 20)
If a + b = 6, what is the value of 3a + 3b?

The answer depends on the value of y.
