Iteration[Function, Number x0, Number n]

Iterates the function n times using the given start value x0.

Examples: After defining f(x) = x^2 the command Iteration[f, 3, 2] gives you the result (3²)²=81;

Another example of the use of this command is the repeated addition of 7 to the number 3:

Let g(x) = x+7. The command Iteration[g, 3, 4] yields the result (((3+7) +7) +7) +7 = 31.
