The question asks, \"Suppose that f(x)=x^2 and g(x)=3x+1. Find f(g(x)) and f(x-1). I have found f(g(x)). The answer would be (3x+1)^2 and simplified it would be 9x^2+6x+2. I am having trouble setting up the f(x-1). Would that be (x^2-1)^2? I am confused. Thank you so much in advance for your help in this matter.  </SPAN>\n" );
