Best ResponseYou've already chosen the best response.0To find f(g(x)) you replace all the x's in f(x) with the expression from g(x).dw:1439418816269:dw

Best ResponseYou've already chosen the best response.0My issue with why I'm confused is when you put the f in the g, i got gx=(4x^2 + x +1)^2 but that doesnt seem right

Best ResponseYou've already chosen the best response.0you are right. I misread it. You just do it the other way around. Replace x in g(x) with 4x² + x + 1

Best ResponseYou've already chosen the best response.0ok do you do (4x^2 + x + 1) * (4x^2 + x + 1) or do you just apply the ^2 one time?

Best ResponseYou've already chosen the best response.0yeah it's a lot to keep track of. I distribute everything in the 1st parentheses to everything in the 2nd and add them all up at the end.dw:1439419351533:dw
