describe how the graphs of these functions are related

Question

anonymous · Answer

$$y = \sqrt {x}$$
$$y = 4\sqrt{x}$$

anonymous · Answer

one is the square root

anonymous · Answer

is the second one 
$$\sqrt[4]{x}$$ or is it 
$$4\sqrt{x}$$ makes a big difference

anonymous · Answer

It's exactly how I wrote it and I wrote the wrong question. Though I fixed it now.

anonymous · Answer

the second one is four times the first one

anonymous · Answer

i am not sure what kind of answer you are looking for

anonymous · Answer

I have to describe how the graphs are similar

anonymous · Answer

Here's the graphs http://www.wolframalpha.com/input/?i=y+%3D+sqrt+%7Bx%7D%3B+y+%3D+4*sqrt%7Bx%7D

anonymous · Answer

be careful when you look at the graphs
it is giving you real and imaginary numbers
make sure to click on "real plot"

anonymous · Answer

This means one square root is positive while another one is negative. 
Let x be the number you are looking for. Your word statement can be written as the following equation
 
                     
 $$\sqrt{x}-(-\sqrt{x}) = 2\sqrt{x}=30 $$ or $$\sqrt{x}=15  and  x= 152=225$$
