Question 1127453
----
1. 
f(x)=x-1  
g(x)= sqrt(x)
h(x)=x-1
----



------------------
a) 
Find f(g(3))
------------------


{{{(sqrt(x))-1}}}
{{{highlight(sqrt(3)-1)}}}



-------------------
b) 
Find f(g(h(x)))
-------------------


{{{g(h(x))=sqrt(x-1)}}}
-
{{{f(sqrt(x-1))=(sqrt(x-1))-1}}}

{{{highlight(f(g(h(x)))=sqrt(x-1)-1)}}}
