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
