One of the functions I am doing a Square Root Function and i start off with the equation:

f(x)=SQRT(x+6) -2

I have to change it to a Shifted, Reflected, and Stretched graph:

Shifted: f(x)=SQRT(x+7)-2

Reflected: f(x)=-(SQRT(x+6))-2

Stretched: f(x)=2(SQRT(x+6)-2

I have already made the graphs and have my equations, but I do not know how to describe what happens between each of the graphs/equations. It only has to be a sentence long.

If found this website to help me see all graphs at once [http://www.walterzorn.com/grapher/grapher_e.htm] and just copied and pasted the equations into writing box

Please tell me if I am unclear, this is my first time posting.
