To complete a function composition, you must substitute one function in the place of x in the other. For example in f(g(x)), you must plug function g into f.
f(g(x))=(4x+1)+8
f(g(x))=4x+9
When finding the composition of functions think of working from the inside to the outside. So, if you have f(g(h(x))), you plug h into g and then you plug the result from that calculation. When there is a number in the place of x, you must plug that number in for x and then work your way out.
