HELP PLS
If f(x) = x-2/x+3 and g(x) = x -4 find g(f(x)) and f(g(x))
:((((( so hard
thank you in advance
+129847 g(f(x)) just means that we are putting "f" into each "x" in g and evaluating
So......
( (x-2) / ( x + 3) ) - 4 =
(x - 2) - 4(x + 3)
_____________ =
x + 3
-3x - 14
_______
x + 3
f(g(x)) (as you may have guessed) means "g" into "'f
So....
(x- 4) - 2
_________ =
(x - 4) + 3
x - 6
_____
x - 1
