Can someone please help me ASAP.....

We have to start with a number $x$ , compute $f(x)$ , and then use this result as input for $g(x)$

When you give $x$ as input to $f$ , it returns $-x^2-1$ :

$x\mapsto f(x)-x^2-1$

Now, $g(x)=x+5$ simply means that $g$ will return its input plus five.

In this case, the input is $f(x)$ , so we have

$g(f(x))=f(x)+5 = -x^2-1+5=-x^2+4$
