Question

Describe how to obtain the graph of y=-2sqrt(x+4)-4 from the graph of y=sqrt(x)

Answer 1

Several concepts are involved here:
1) vertical compression/stretching (stemming from that "2" in front of Sqrt(x+4) );
2) vertical translation of the graph
3) horizontal translation of the graph
4) flipping the graph about the horizontal (x-) axis.
Which of these are you already familiar with? Apply them.

Answer 2

I don't really understand

Answer 3

What previous experience have you had, if any, with any of these concepts? I'm sure you've seen some of them before.

I need to know where you stand in preparation for doing this type of problem. Have you a textbook, or online materials, that give(s) examples of translations, stretching, compression, and so on? I'd be happy to build upon what y ou already know, but would much prefer not to explain every detail from scratch.

Answer 4

Where have you gone in the past when you've needed examples of how to solve a given type of problem?
