Question

f(x) = |3x + 4| +2
g(x) = 4

find (f + g)(x).
a. ( f + g)(x) = |3x + 4| + 6
b. ( f + g)(x) = |3x| + 10
c. ( f + g)(x) = |3x + 6| + 4
d. ( f + g)(x) = |3x + 10|

Answer 1

Answer:

A

Step-by-step explanation:

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

= ( |3x + 4| + 4) + (2)

= |3x + 4| + 4 + 2

= |3x + 4| + 6
