Given g(x) = print_coeff(m,1)x print_const(b), find g(print_coeff(n,1)a)

I was told that the answer for this is a. However, I have no idea how to solve it. Please help me understand.

I have no idea how to interpret what you have written. It is not standard algebraic notation.

That is what I thought.. Nevertheless, they are offering extra credit to solve it.

I apologize for the confusion. It seems that the notation used in your question is not clear or standard. In order to help you solve the problem and understand it, I would need a clearer explanation of the given functions and their meanings.
