Answer:
4/5
Step-by-step explanation:
6x + 3 = 2x + 8
-3 -3
6x = 2x + 5
-2x -2x
4x = 5
x = 4/5
Given that

attains a maximum at

, it follows that

at that same point. So integrating once gives



and so the first derivative is

.
Integrating again, you get


You know that this curve passes through the point (2, -1), which means when

, you have

:


and so
Go to google they have the answer
