Question

Let f(x) = 7x - 6 and g(x) = 3x + 4.  Find f(x) + g(x).

Answer 1

Just add both the functions.


\(\Large \color{MidnightBlue}{\Rightarrow 7x - 6 + 3x + 4 }\)
\(\Large \color{MidnightBlue}{\Rightarrow 10x - 2 }\)

\(\Large \color{MidnightBlue}{\Rightarrow 2(5x - 1) }\)
If needed. You may factor like I have done in this step.
