I'm using the function 'Interpolation' which takes pairs of x and y values.
f = Interpolation[{{-1, (8/3)}, {0, 2}, {2, (2/3)}, {3, 0}}]
I can now plot the function via 'Plot[f[x], {x, -1, 5}]' and determine y values to arbitrary x values via 'f[x]'.
What I'm not able to to is get the function definition (in this case 'f(x) = -2/3x + 2').
Is there a way to achive this?
Thanks in advance
Toby
