Iteration Command

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
• To obtain the repeated addition of 7 to the number 3: if g(x) = x+7 then Iteration[g, 3, 4] yields (((3+7) +7) +7) +7 = 31.
