The earth exerts a gravitational force of f(f)=(2.99x10^16)/r^2 newtons on an object with a mass of 75kg located r meters from the center of the earth. find the rate of change of force with respect to distance.

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8
