Question

f as a function of x is equal to the square root of quantity 4 x plus 6, g as a function of x is equal to the square root of quantity 4 x minus 6 Find (f + g)(x). x times the square root of 8 4x square root of 8 times x The square root of quantity 4 times x plus 6 plus the square root of quantity 4 times x minus 6

Answer 1

`\large \boxed{{√(4x+6) + √(4x-6) }}`

Explanation:

`f(x)=√(4x+6)`

`g(x)=√(4x-6)`

`(f+g)(x)`

`f(x)+g(x)`

Add both functions.

`(√(4x+6) )+ (√(4x-6) )`

Answer 2

Last one

Explanation:

The function f is:

● f (x)= √(4x+6)

The function g is:

● g(x) = √(4x-6)

Add them together:

● f+g (x)= √(4x+6 )+ √(4x-6)
