Good evening ,
You need to verify the answer!!!

Step-by-step explanation:
Look at the photo below for the answer.
:)
Y = -3/8x + 51/8
Or y = -3/8x + 6. 4
Y=-2x^2-3x+4
dy/dx=-4x-3, d2y/dx2=-4
When the velocity, dy/dx=0, then y(x) is at an absolute maximum because the acceleration is a constant negative, -4.
dy/dx=0 only when -4x-3=0, -4x=3, x=-3/4
y(-3/4)=5.125
So the maximum value of y is 5 1/8
