Answer 1

Answer:

A.34

Step-by-step explanation:

f(4)=17

2f(4)=34

if I've understood it :/ but I've didn't understood about g(x)

Answer 2

Answer:

A. 34

Step-by-step explanation:

f (x) = x² + 1. f (4) simply means we should replace X with 4

so it will be

f (4) = 4² + 1

= 16 + 1

= 17

so now 2. f ( 4) means:

2. 17

which gives :

34

hope this helps
