_____
Graph: f(x) = Öx + 2.
Can you help me? Thank you so much!

Get some points.  Since the domain is [-2,oo)
choose points starting with -2 and larger values
which are 2 less than a perfect square, although
you can substitute any value in that domain and
plot the decimal val;ue.

 x   f(x)
----------
-2 |  0
-1 |  1
 2 }  2
 7 |  3
14 |  4

Plot them:

 

Now connect them with a smooth curve:
