Question 19213
How do the graphs of y=X+3 (in square root) compare the graph of y=x (insquare root) where x is greater or equal to 0. And can you also graph y=f(x)+5
             And can you also please tell me how do you graph functions and etc. Thank you.
give different values to x and find corresponding value of y...for example..when x=1..we get y=sqrt.(x+3)=sqrt.4=+2 or -2..similarly solve for others....
	y=sqrt(x+3)						
x	0	1	2	3	-1	-2	-3
y	1.73	2	2.23	2.45	1.41	1	0
y	-1.73	-2	-2.23	-2.45	-1.41	-1	0
we get the graph as follows
{{{ graph( 300, 200, -3, 6, -5, 5, +(x+3)^0.5,-(x+3)^0.5) }}}

	y=sqrt(x)						
x	0	1	4	9	16	25	36
y	0	1	2	3	4	5	6
y	0	-1	-2	-3	-4	-5	-6
we get the graph as follows
{{{ graph( 300, 200, 0, 36, -10, 10, +(x)^0.5,-(x)^0.5) }}}

And can you also graph y=f(x)+5..THIS CANNOT BE DONE UNLESS WE KNOW WHAT IS f(x)...CHECK THE PROBLEM AGAIN
