finding indicated composite functions

[ljk]

:? What steps do I take to find the indicated composite funtions:

f(x)=5x+4
g(x)=4x+5

f*g(1)=______________
g*f(1)=________________

Thanks,

when you say f*g(1) do you mean f(g(1))? Those would be function compositions, and not just simply multiplication....unless you mean multiplication.
