Which graph best shows the function

anonymous · Answer

$$y=\sqrt{x+2}$$

anonymous · Answer

Draw a chart with values for x and then compute the value of y. Sum as if x = 2 then y = sq root of 4    (2+2)  which is 2.  Then do it for x= 7..what do you get for y?

im like really confused

You have a graph correct. The graph requires that you need to coordinates (X,Y)..You understand that?

anonymous · Answer

yes

anonymous · Answer

The equation is like a computer. You input a value (x) and the out put is (y).  This if I input a value of 2 for (x)...what would my output be for (y)? 
If I input a value of 7 for (x)..what would be my output for (y)?
Lastly are there any values that (x) cannot be?

anonymous · Answer

4 and 9

anonymous · Answer

im not really sure

anonymous · Answer

That is correct for the first two so on your graph you would have (2,4) and (7,9) as two points then connect them with a continuous line. But.are there values the x cannot be. Remember you cannot have a square root of a negative value. So (x) cannot never be less than what?

anonymous · Answer

Try x = -2  what wouldyou get for y?
Than try x = -3 what do you get?

anonymous · Answer

um 0 and -1

anonymous · Answer

You acnnot have a square root of a negative number thus your lowest value for x would be -2 and the coordinates would be (-2,0) for (x,y). Now plot all that on the graph and see which one fits. The point (-2,0) shoul be the starting point and be solid

anonymous · Answer

graph of y equals square root of x minus 2 

 graph of y equals cube root of x plus 2 

 graph of y equals square root of x plus 2 

 graph of y equals cube root of x minus 2

anonymous · Answer

those r the answers but they r graphs

anonymous · Answer

im not sure which one it would be

anonymous · Answer

the 2 middle ones start at like close to one and then the others start at 2 on the x axis
