Select the one true statement.
Consider a C∞ function f: R" → R and two multi-indices a, ß € N".
If |a| = |B, then gº f = 8³ f.
Consider a C∞ function f: R" → R and two multi-indices a, ß € N".
If a! = 3!, then 8° f = 8³ f.
O Any polynomial of any number of variables is of class C¹k for any k € N+.
O For any polynomial p of any number of variables, there is a multi-index a
such that 8p is not continuous.
