Answer:
A
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= 3x² + 4x - 8 - (2x - 5) ← distribute parenthesis by - 1
= 3x² + 4x - 8 - 2x + 5 ← collect like terms
= 3x² + 2x - 3 → A

[tex]3x^2 - 4x - 8 - ( 2x - 5 )[/tex]
[tex]3x^2- 4x - 8 - 2x + 5[/tex]
[tex]3x^2 +4x - 8 - 2x + 5[/tex]
[tex]Solution = 3x^2+2x-3[/tex]
