Question

is the answer to this a horizontal stretch by a factor of 9???vertical stretch by factor of 3horizontal translation 2 units lefthorizontal stretch by factor of 9vertical translation 2 units up

Answer 1

We have

`f(x)=log_3(x)`

and

`g(x)=log_3(9x)`

We rewrite g(x)

`g(x)=(log(x)+log(9))/(log\left(3\right))`
`g(x)=\log_3\left(x\right)+2`

As we can see we have a vertical translation 2 units up

ANSWER

vertical translation 2 units up
