$\large\rm \color{royalblue}{f(x)=x+7},\qquad\qquad \color{orangered}{g(x)=x-8}$

Let's check out this first one :)$\large\rm (\color{royalblue}{f}+\color{orangered}{g})(x)=\color{royalblue}{f(x)}+\color{orangered}{g(x)}$When we plug in our functions we get,$\large\rm \color{royalblue}{x+7}+\color{orangered}{x-8}$And then you can simplify by combining like-terms.

I know the notation can be a little hard to get used to, hopefully this makes a little sense thoguh
