Answer 1

Answer:

D

Step-by-step explanation:

$f(x)=2x^2+1\\g(x)=x^2-7\\(f-g)(x)= (2x^2+1)-(x^2-7)=x^2+8$

Therefore, the correct answer is choice D. Hope this helps!

Answer 2

Answer:

x² + 8

Step-by-step explanation:

We just need to subtract these two equations

• (2x² + 1) - (x² - 7)
• Distributing the negative we have: 2x² + 1 - x² + 7
• Then combining like terms we have x² + 8
