Question

If F(x) = 3 log x and G(x) = x^2 + 1, find G[F(x)].

Answer 1

G[F(x)] = G[3logx] = (3logx)^2 + 1 = 9(logx)^2 + 1 = \(\large 9log^2x \)

Answer 2

that last step should be : \(\large 9log^2x+1\)

Answer 3

well these are the answers it has given me to choose from
(3logx)² + 1
3log(x² + 1)
3(x² + 1)logx

Answer 4

i simplified too much...
look at the steps i showed... it is one of those choices..
