Answer: A. f(g(x)) =x and g(f(x))=x and f and g are inverses.
Step-by-step explanation:
A function <em>g</em> is the inverse of function <em>f</em> if
<em>f(g(x)) = g(f(x))=x</em>
Given: f(x)= x+4 , g(x) = x-4
f(g(x)) = f(x+4) = (x-4)+4
= x-4+4 = x
i.e. f(g(x)) =x
g(f(x))= g(x-4) = (x-4)+4 =x
i.e. g(f(x))=x
Hence, f(g(x)) =x and g(f(x))=x and f and g are inverses.

Answer:
-7g-3
Step-by-step explanation:
in order to evaluate for this mathematical expression, we need to consider the negative sign carefully and then open the bracket then evaluate.
<u>solutuion</u>
-3 (5 g +1) + 8 g
-15g -3 + 8g
-15g +8g -3
-7g-3
