if f(x) = -3 -5 and g(x) =4x - 2, find (f+g)(x)

If Fx 3 5 And Gx 4x 2 Find Fgx class=

Sagot :

According to the problem, we just have to sum the given functions f(x) plus g(x)

[tex](f+g)(x)=f(x)+g(x)=-3x-5+4x-2[/tex]

We just have to reduce like terms. -3x and 4x are like terms; -5 and -2 are like terms.

[tex](f+g)(x)=x-7[/tex]

Hence, the right answer is B.
