What tools are you allowed/supposed to use?

anonymous · Answer

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

anonymous · Answer

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

Oh, choices, that makes things a bit easier.

ddcamp · Answer

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

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