Which Combination could create the function: x^2+3

f(g(x)) where

g(x) = x^2
f(x) = x+3

To create the function \(x^2+3\), you need to combine the terms of the function in a way that properly represents the given expression. Here's how you can do it:

1. Start with the function \(f(x) = x^2\).
2. To get the desired function, you need to add 3 to \(f(x)\). Thus, the combination that creates the function \(x^2+3\) is:
\[f(x) + 3 = x^2 + 3\]

Therefore, the combination needed to create the function \(x^2+3\) is \(f(x) + 3\), where \(f(x) = x^2\).
