FunctionAnalytic

FunctionAnalytic[f,x] tests whether f(x) is an analytic function for x∈Reals.

FunctionAnalytic[f,x,dom] tests whether f(x) is an analytic function for x∈dom.

FunctionAnalytic[{f1,f2,…},{x1,x2,…},dom] tests whether f1(x1,x2,…),f2(x1,x2,…),… are analytic functions for x1,x2,…∈dom.

FunctionAnalytic[{funs,cons},xvars,dom] tests whether funs(xvars) are analytic functions for xvars in an open set containing the solutions of the constraints cons over the domain dom.
