Let f(x) = –4x and g(x) = 5x2. Andrew finds the composition [f o g](x) as shown below. What error did Andrew make? = 5(–4x)2 = 5
Elden [556K]
F(g(x)) means you take the g function and put it into x in the f function.  He took the function and put it into the g, which was the incorrect order.  He should have had this: f(g(x))=-4(5x^2)
