Question

Due in 4 hours, 30 minutes. Due Wed 04/27/202For the functions f(x) =3x2 + 3.25 and g(x) = 4x2 – 2 + 3, find:a. (f + g)(x) =Previewsyntax errorb. (f + g)(3)**c. (f - g)(x) =*

Answer 1

Okay, here we have this:

Considering the provided functions, we are going to perform the requested operations, so we obtain the following:

`\begin{gathered} (f+g)(x) \\ =(3x^2+3x-5)+(4x^2-x+3) \\ =7x^2+2x-2 \end{gathered}`
`\begin{gathered} (f+g)(x) \\ =(3x^2+3x-5)+(4x^2-x+3) \\ =7x^2+2x-2 \end{gathered}`

`\begin{gathered} (f+g)(3) \\ =7(3)^2+2(3)-2 \\ =7(9)+6-2 \\ =63+4 \\ =67 \end{gathered}`

`\begin{gathered} (f+g)(3) \\ =7(3)^2+2(3)-2 \\ =7(9)+6-2 \\ =63+4 \\ =67 \end{gathered}`
