This is a continuation from my previous response because I was unable to edit that answer in order to upload the graphs.
#4 Answer is y =
(
)
see the first attachment for the graph
#5 Here is an example of two unique transformations from the equation provided: y = 2(
)
shift the graph 1 unit up → y = 2(
) + 1
then shift the graph 2 units to the left → y = 2(
) + 1
