Question

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

Answer 1

Calculate y after assigning a value to x

Explanation:

If x is -2, your function `y=0`
If x is -1, your function `y=sqrt1`
If x is zero, your function `y=sqrt2`
If x is 1, your function `y=sqrt3`
If x is 2, your function `y=sqrt4=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]}
