Y=-x^2-2
dy/dx=-2x and d2y/dx2=-2
Since acceleration is a negative constant, when the velocity equals zero, it will be an absolute maximum for y(x)
dy/dx=0 when -2x=0, x=0
y(0)=-2
So the vertex is at the absolute maximum, which is the point (0,-2)
Answer:
n(-9+ n) =0
Step-by-step explanation:
-9n+n^2=0 Kind of use 'reverse distributive' property
n (-9 + n) = 0
The turning point is at (2, 3)
F(-7) = -1.
1.6 is in between those 2 numbers
