Composing functions means that the input of the outer functions is the output of the inner function.
In fact, you can rewrite the circle notation as

So, we can substitute g(x) with its expression:

And since f(x)=x+5, we simply have to add 5 to its input:

Similarly, we have, substituting f with its expression,

And since g(x)=4x+2, we have to multiply the input by 4 and add 2:

Answer:
Open dot at -1 and shaded to the right.
Step-by-step explanation:
First you have to solve the inequality are you get |y|>-1
Now you can plot the inequality by placing an open dot on -1 since the inequality is greater than.
Since the inequality is greater than, you also have to shade when all y values are greater than -1 so you would shade to the right.
