Giving that f(x)=3x^2-x-5, g(x)=-1 what is (f+g)(x)
[tex]\begin{gathered} f(x)=3x^2-x-5 \\ g(x)=-1 \end{gathered}[/tex][tex](f+g)(x)=f(x)+g(x)[/tex]Adding up the two function:
[tex]\begin{gathered} (3x^2-x-5)+-1 \\ simplify\text{ the bracket} \\ 3x^2-x-5-1 \\ 3x^2-x-6 \end{gathered}[/tex]Therefore the correct answer is:
[tex](f+g)(x)=3x^2-x-6[/tex]
