Question

Which of the following transformations are used when transforming the graph of the parent function...

Answer 1

1. 1st transformation is translation the parent function
`y=\log_5x` 6 units to the right to get the function
`y=\log_5(x-6).`

2. 2nd transformation is reflection the function
`y=\log_5(x-6)` over the x-axis. This transformation gives you the function
`y=-\log_5(x-6).`

3. 3rd transformation is vertical stretch of the function
`y=-\log_5(x-6)` by a factor of 2 to get the function
`y=-2\log_5(x-6).`

Only last two are present in options, then

answer: C and D.
