Please post code as text, not as screenshot. Text can be used by copy&paste, while posting an answer based on screenshots wastes time by re-typing your code.

The function needs 3 inputs:

function x = logictic1(r, x0, n)

You provide 1 inut only:

logistics1(1)

Then the values of xo and n are missing. So "Not enough input arguments" is a clear statement.
