Answer:
x² + 16x + 64
Step-by-step explanation:
To find f(g(x)) , substitute x = g(x) into f(x), that is
f(x + 7)
= (x + 7)² + 2(x + 7) + 1 ← expand (x + 7)² using FOIL
= x² + 14x + 49 + 2x + 14 + 1 ← collect like terms
= x² + 16x + 64
The correct answer is B.
16-9=7
So, 7+9=16.
If we add to 9 only 1 (out of those 7) we have then 10, remaining 6.
9+1=10
Now, if to 10 we add the remaining 6 we will have the final 16.
10+6=16
16-9=7 <=> 9+7=16 <=> (9+1)+6=16
