How do you graph y=sqrt(x+2)?

Jul 31, 2017

Calculate y after assigning a value to x

Explanation:

If x is -2, your function $y = 0$
If x is -1, your function $y = \sqrt{1}$
If x is zero, your function $y = \sqrt{2}$
If x is 1, your function $y = \sqrt{3}$
If x is 2, your function $y = \sqrt{4} = 2$
Your function is not defined if x is less than -2.

You can graph now:

graph{sqrt(x+2) [-5.75, 14.25, -5.69, 4.31]}
