Answer:

-3, 7, 8

Step-by-step explanation:

You can fill in the boxes from the table values as shown in the attachment.

The leading coefficient is negative because the parabola opens downward. The value of it is the change in y-value as x changes by 1 unit either side of the vertex.

The vertex is identified by the fact that the y-values are symmetrical either side of the vertex.

A particle moves along a straight line with equation of motion s = f(t), where s is measured in meters and t in seconds. Find th

Lena [83]

F(t) = (t^-1) - t
Taking derivative:
f'(t) = d/dt(t^-1) - t) = d/dt(t^-1) - d/dt(t) 
f'(t) = -1(t^-2) -1
= -t^-2 - 1 
f'(t) = v(t),
It can be also written as :
-1/t^2 - 1 

So v(3) = -1/(3^2) - 1 = -1/9 - 1 = -10/9
