g(x)=3x^(2)+5x+2 h(x)=2x+1 " 1. "f(x)+g(x)

\( f(x) + 3x^2 + 5x + 2 \)

The question asks for the sum of \( f(x) \) and \( g(x) \), where \( g(x) = 3x^2 + 5x + 2 \) and \( h(x) = 2x + 1 \). The function \( h(x) \) is not relevant to this question.To find \( f(x) + g(x) \), we simply add the two functions together. Since \( g(x) = 3x^2 + 5x + 2 \), the sum \( f(x) + g(x) \) would be \( f(x) + 3x^2 + 5x + 2 \).Note that \( f(x) \) is an unknown function, so it remains as is in the sum. Therefore, the answer is \( f(x) + 3x^2 + 5x + 2 \).
