the question is:

f( x)=2x-1 g(x)=3-2x h(x)= 1/4(5-x)

a) Find a formula for k(x) where k(x)=f [g(x)]

b) Find a formula for h [k(x)]

c) What is the connection between the functions h and k.

Please help, I really have no idea what to do.

Thanks :)

$\displaystyle (f\circ g)(x)=2(3-2x)-1$

Similar with b).
