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%28+300%2C+200%2C+-3%2C+6%2C+-5%2C+5%2C+%2B%28x%2B3%29%5E0.5%2C-%28x%2B3%29%5E0.5%29+

give different values to x and find corresponding value of y...for example..when x=1..we get y=sqrt.(x)=sqrt.1=+1 or -1..similarly solve for others....
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%28+300%2C+200%2C+0%2C+36%2C+-10%2C+10%2C+%2B%28x%29%5E0.5%2C-%28x%29%5E0.5%29+
And can you also graph y=f(x)+5..THIS CANNOT BE DONE UNLESS WE KNOW WHAT IS f(x)...CHECK THE PROBLEM AGAIN
