 Question 69760: Would someone please help me with this problem... Given f(x)=x^2+3 and g(x)(sqrt)2-x find f o g(x). a.5-x b.1-x c (sqrt)5-x^2 d. 7+x^2 ThanksAnswer by stanbon(57303)   (Show Source): You can put this solution on YOUR website!Given f(x)=x^2+3 and g(x)=(sqrt)2-x find f o g(x). -------- f[g(x)] = f[ sqrt2 - x] = (sqrt2 - x)^2 + 3 =2-2sqrt2x+x^2 + 3 = x^2 - 2sqrt2x +5 -------- Sorry, this is the answer as you have posted the problem, but the answer is not among the ones you listed. ---------- Cheers, Stan H.
