If ƒ(x) = x − 4 and g(x) = 3x + 5, find (ƒ + g)(x).

siniylev [52]

Answer:

$(f+g)(x)=4x+1$

Step-by-step explanation:

We are given the two functions:

$f(x)=x-4\text{ and } g(x)=3x+5$

And we want to find:

$(f+g)(x)$

This is equivalent to:

$=f(x)+g(x)$

By substitution:

$=(x-4)+(3x+5)$

Rearranging yields:

$=(x+3x)+(-4+5)$

Combine like terms:

$=4x+1$

Hence:

$(f+g)(x)=4x+1$
