The function f on R is defined by
F(X)={x-3 if x<=3
{x/4 if x>3
Find the value of

ii. f [f(8)]

okay ... i'll do the first example ... you do the rest
20 > 3 then F(x) = x/4 .... right??
f(20) = 20/4 = 5
again, 5>3, so F(x) = x/4 ... so
f(5) = 5/4 = 1.25 :D

f(8)=x/4
=8/4
=2
so 2<3 so f(x)= 2-3= -1?
