    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?
