Question

If f(x) = 3x - 2 and g(x) = 2x - 1, find (f +g) (x)A. 5x - 3B. x - 1C. 5x - 1D. x - 3 Can you please go in to detail on how to do these.I really don't understand how.

Answer 1

We have to sum two functions, so:

$\begin{gathered} f(x)=3x-2,g(x)=2x-1 \\ (f+g)(x)=f(x)+g(x) \\ (f+g)(x)=(3x-2)+(2x-1) \\ (f+g)(x)=3x-2+2x-1 \\ (f+g)(x)=5x-3 \end{gathered}$

The correct answer is A.
