Question

I need help with this

Answer 1

`(f+g)(x)=7x^2-3x-5`

Explanation:

Step 1: What you are given & need to find

• 
  `f(x)=√(16x^4)`
• 
  `g(x)=3x^2-3x-5`
• 
  `(f+g)(x) = ?`

Step 2: Set up the problem

• 
  `(f+g)(x) = f(x)+g(x)`
• 
  `(f+g)(x)=(√(16x^4) )+(3x^2-3x-5)`

Step 3: Simplify

• 
  `(f+g)(x)=√(16x^4) +3x^2-3x-5`
• 
  `(f+g)(x)=4x^2+3x^2-3x-5`
• 
  `(f+g)(x)=7x^2-3x-5`
