Best ResponseYou've already chosen the best response.1First, we need to find g(2). To find g(2), plug x=2 into g(x) \(g(x) = x^2+5x\\~\\ g(\color{red}{\textbf{2}}) = (\color{red}{\textbf{2}})^2+5(\color{red}{\textbf{2}})\)

Best ResponseYou've already chosen the best response.1Right. So \(g(2) = 14\) Now what is \(\text4[g(2)]\)?
