Define a polynomial function in Julia

I want to create the function using Polynomials package in Julia, while c is a Vector and n is the length of the Vector. I can make it in JuMP package but not in Polynomials.

Any idea how to create this function?

Just call Polynomial on this vector c.

julia> c = [1, 2, 3, 4]
4-element Vector{Int64}:
 1
 2
 3
 4

julia> p = Polynomial(c)
Polynomial(1 + 2*x + 3*x^2 + 4*x^3)

julia> c = [2, 4, -8, 0, 0, 1]; 

julia> p = Polynomial(c)
Polynomial(2 + 4*x - 8*x^2 + x^5)

julia> p(2) #evaluate the polynomial at x = 2
