B) - 4

Step-by-step explanation:

To solve g (f (3)), we first have to solve f (3):

Since f (x) = - x + 4, f (3) = - 3 + 4 = 1

Now we have to solve g (1), since that is what f (3) left us;

Since g (x) = x^2 - 5, g (1) = 1^2 - 5 = 1 - 5 = - 4

If f (x) = - x + 4 and g (x) = x^2 - 5, then g (f (3)) = ?A) - 8B) - 4C) - 3D) 0
