How to find value of function for array of inputs ?

Lets say f(x) is user inputed function and I have some values of x stored in array, Now I have to find the value of the function for each value of x.

i.e, if I have f(x) as x*2 [This is user-input]

then If i have x = [1,3,4,6]

and I need an other array which the value of f(x)

y= [1,9,16,36] as my answer.

Is there any function that will let evalute the same at once ?
