Answer:
Step-by-step explanation:
Let X be par.
Jenny made x-1 strokes
Jérôme made x+4 strokes.
So, we can use the amount of strokes made, but we have to use absolute value brackets ( | | )
|-1| + |4| = 5.
Jérôme made 5 more strokes than Jenny
Y2-y1 / x2-x1
-1-4 / 2-(-3)
-5/5
-1
So the answer is A
First, I should point out that g(x) should be written as g(x)=(x+2)/3, otherwise the problem is confusing.
(A) 
(B) Since 
and 
, it holds that
for all x. This means the composed functions are *identical*
If you can give me more information on this I could help you a bit more respond.
