Answer:

[tex](f+g)(x)=7x^2-3x-5[/tex]

Step-by-step explanation:

Step 1: What you are given & need to find

  • [tex]f(x)=\sqrt{16x^4}[/tex]
  • [tex]g(x)=3x^2-3x-5[/tex]
  • [tex](f+g)(x) = ?[/tex]

Step 2: Set up the problem

  • [tex](f+g)(x) = f(x)+g(x)[/tex]
  • [tex](f+g)(x)=(\sqrt{16x^4} )+(3x^2-3x-5)[/tex]

Step 3: Simplify

  • [tex](f+g)(x)=\sqrt{16x^4} +3x^2-3x-5[/tex]
  • [tex](f+g)(x)=4x^2+3x^2-3x-5[/tex]
  • [tex](f+g)(x)=7x^2-3x-5[/tex]
