Find a second-order formula for approximating f'(x) by applying extrapolation to the two-point forward-difference formula. (1) Develop a first-order method for approximating f"(x) that uses the data f(x - h), f(x) and f(x 3h) only. Find the error term.

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

step-by-step explanation:

2*2=3

two times two is four

i dont understand what you mean so pls comment
