2.)If f(x)=3x,g(x)=x3,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(x3)
3(he square root of 253
3(53)
159=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(1.73)
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?
