If f(x)=x/2 and g(x) = x-3,what is the value of g(f(8))

Answers

Comment. The first thing to do is find out what f(x) put into g(x) is and what it means. Step One Put f(x) into g(x). This means wherever you see an x in g(x) you put f(x) g(x) = x - 3 g( f(x) ) = f(x) - 3 g( f(x) ) = x/2 - 3 Step Two When you know what g(f(x)) you now put an 8 wherever you see an x. Find g(f(8)) = x/2 - 3 g(f(8)) = 8/2 - 3 g(f(8)) = 4 - 3 g(f(8)) = 1 1 <<<<< answer.

F(x) = x/2 g(x) = x - 3 f(8) = 8/2 = 4 g(f(x)) = 4 - 3 = 1 Answer g(f(8)) = 1
