Hello!
***
(fg)(-6) essentially means f(g(-6)) -- that is, you find g(-6) by plugging -6 into the g function, then plug the resulting value into the f function.
***
First, let us find g(-6):
g(x) = x - 4
g(-6) = -6 - 4 = -10
***
Now, let us plug that into f to find f(g(-6)):


***
Therefore, (fg)(-6) = 101
Let me know if you need any further clarification! =)
