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.
