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?
