Question

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 (x-6)/(2)+4x^2+x-4`

`\\ \tt\longmapsto (x-6+8x^2+2x-8)/(2)`

`\\ \tt\longmapsto (8x^2+3x-14)/(2)`

`\\ \tt\longmapsto 4x^2+(3)/(2)x-7`

Answer 2

• C. 4x² + 3x/2 - 7

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
