Question

What exponential function is the best fit for the data in the table?

x f(x)
3 10
4 16
5 28

Answer 1

What tools are you allowed/supposed to use?

Answer 2

tools? i'm not sure if we're supposed to use any tools but we basically just have to to figure out the equation

Answer 3

the answer choices are
a. f(x) = 3(2)^(x − 2) + 4
b. f(x) = 3(2)^(x − 2) − 4
c. f(x) = 1/3(2)^(x − 2) + 4
d. f(x) = 1/3(2)^(x − 2) − 4

Answer 4

Oh, choices, that makes things a bit easier.

Answer 5

Since you have choices, the first thing I would do is try each of them with 3, and see what works.

Answer 6

You will also have to define "best fit". What are the criteria for determining "best". How do you know one is better than another?
