Answer:
[tex]g(x)=x-1\\g(f(x))=(-2x-5)-1\\g(f(x)=-2x-6[/tex]
Step-by-step explanation:
So this is a composition of functions. Think back to solutions of equations. You would have to put the equation into the other equations. It's like this!
So I graphed it like this on desmos:
[tex]g(x)=x-1\\g(f(x))=(-2x-5)-1\\g(f(x)=-2x-6[/tex]
