Homework Help: math

Posted by Leo on Saturday, April 6, 2013 at 6:52pm.

2.)If f(x)=3x,g(x)=x-3,and h(x)= the square root of x, find (fogox)(X). I really didn't get this will someone please show me how to do it?

This I what I did to solve for it:
3(x-3)
3(he square root of 25-3
3(5-3)
15-9=6

Ok here is another way I solved for it but I am still not sure if I am doing any of the work right.

f(g(h))(25)
f(g(square root of f(x)))(25)
f(g(1.7))(25)
f(1.7-3)
F(-1.3)
f(25)=3(25)
f(25)=75

Which one is correct and if they are both wrong will you help me get the right answer and understand how to do it?
