Given f(x)=xsquare-4, g(x)=x-1, and h(x)=3x+1

1. f(g(h(x))) and 2. g(h(f(x)))

Incase you can't answer number 2, can u just write a step to do like the others. Thank you very much i appreciate it. There is no square symbol so i had to write it out. I have others questions on other harder topics but their are no symbols to be used so do you know how i can get to type it on.
