I have the coefficients of my desired polynomial in an array CoefArr (I'm new to mathematica, so I think of everything as arrays, it is actually a list I believe) starting with the constant at index 1.
I want to turn this into a function I can evaluate like this:
f[x_] := CoefArr[][] + x*CoefArr[][] + etc.
So I can just do f and get the answer. Is there a way to do this in general?
