Answer:
Option B (n³ + 4n² + 8n - 16)
Step-by-step explanation:
In this question we have to add two expressions given
( 2n³ + 4n² - 7 ) and ( -n³ + 8n - 9 )
( 2n³ + 4n² - 7 ) + ( -n³ + 8n - 9 )
Now we group the similar terms
( 2n³ - n³ ) + 4n² - ( 7 + 9 ) 8n
= n³ + 4n² - 16 + 8n
= n³ + 4n² + 8n - 16
Option B (n³ + 4n² + 8n - 16) is the correct answer.

Your answer is D hope this helps!!

c^6 d^18 x^3..........
if given f(-x)=x-7, then f(h(x))=-2x-10
or if given f(x)=x-7, then f(h(x))=2x-4
if given f(-x)=x-7
f(-x)=x-7 => f(-(-x))=(-x)-7 =>f(x)= -x-7
f(h(x))=f(2x+3)= -(2x+3)-7 = -2x-3-7 = -2x-10
if given f(x)=x-7
f(h(x))=f(2x+3)=2x+3-7=2x-4
