Thread: Find a function with given points

Okay, so I have a math problem where I am given the fallowing points:

X
1.7
2.0
2.9
4.1
5.6
6.3
7.0
8.0
10.0
13.9
Y
42.0
21.0
10.3
6.8
5.1
4.8
4.4
4.1
3.7
3.2

Now I have to find a function that models those points and create it by hand.

I know one of the ways to do it is an inverse function but I can't figure out how to create one.

Then I also found the formula He^-kx may represent that function but I have no clue what H, e, or k represent in the equation.

Can anyone help me?

Sorry about the way the data was posted.

It looked right when I was writing it.
