Best ResponseYou've already chosen the best response.1cos(x) maxes out at 1. It's the largest it can get we can replace x with any complicated expression we want so cos(BLAH) also maxes out at 1 What does this mean? It means that if we want to max out y, we just replace `cos(5pi/6(x+4))` with the largest numeric value it can be, which is 1

Best ResponseYou've already chosen the best response.1so `y=3+4cos(5pi/6(x+4))` turns into `y=3+4(1)` from here you just calculate `3+4(1)`
