Answer: Option B

[tex](f + g)(x)=x^2 - x - 3[/tex]

Step-by-step explanation:

In this problem we have the function

[tex]f(x) = 2x - 1[/tex]

and the function

[tex]g(x) = x^2 - 3x - 2[/tex]

They ask us to perform the operation:

[tex](f + g)(x)[/tex]

Therefore we must perform the algebaic summa of the function f plus the function g

[tex](f + g)(x)=f(x) + g(x)[/tex]

[tex](f + g)(x)=2x - 1 + x^2 - 3x - 2[/tex]

Now we siplify the expression

[tex](f + g)(x)=x^2 - x - 3[/tex]
