Is my answer correct?

Suppose that (-24,12) is a point of some function y=f(x).

Find its image point if it has the following transformations defined by

My solution

it shifts left 3 units ... (-27,12)
it is vertically expanded by 4 ... (-27,4
it shifts 5 units up ... (-27,53)
the y coordinate is square-rooted ... (-27,)
it shifts 2 units down ... (-27,)

I don't have the answer for this question. Could someone please check and see if it is correct? Thanks.

Re: Is my answer correct?

When I showed my solution to a friend of my friend, he said that it is wrong. I really don't see why it is wrong.

Please help me. Thanks.
