Question

Decide if each of the statements below are true or false based on the table of data below. Make sure to calculate the first and second differences before making your choices.

Answer 1

we have

x f(x)

2 325 First difference Second difference

4 388 --------> (4-2)=2 -----------> 388-325=63

6 437 ---------> (6-4)=2 --------> 437-388=49

8 472 --------> 8-6=2 ----------> 472-437=35

10 493 --------> 10-8=2 -------> 493-472=21

12 500 -------> 12-10=2 -------> 500-493=7

statements

1) true

2) false

3) false

4) Verify

437/388=1.1263

472/437=1.0801

therefore

is false

N 8

To better understand this problem, plot the given function

see the attached figure

give me a minute to plot the function

therefore

the function that best represent the function is a linear equation
