PLEASE HELP.................................................

Answer 1

• f(x)=x/2-3=x-6/2

$\\ \tt\longmapsto (f+g)(x)=f(x)+g(x)$

• Put values

$\\ \tt\longmapsto \dfrac{x-6}{2}+4x^2+x-4$

$\\ \tt\longmapsto \dfrac{x-6+8x^2+2x-8}{2}$

$\\ \tt\longmapsto \dfrac{8x^2+3x-14}{2}$

$\\ \tt\longmapsto 4x^2+\dfrac{3}{2}x-7$

Answer 2

Answer:

• C. 4x² + 3x/2 - 7

Step-by-step explanation:

Given:

• f(x) = x/2 - 3
• g(x) = 4x² + x - 4

Find (f + g)(x):

• (f + g)(x) =
• f(x) + g(x) =
• x/2 - 3 +  4x² + x - 4 =
• 4x² + 3x/2 - 7

Correct choice is C
