you do not need to graph this to do it

2. misty1212

put in the number for x, see if you get the y

3. anonymous

Oh really okay

4. misty1212

you are right however

5. misty1212

it is $f(x)=\sqrt{x+6}+2$right?

6. anonymous

yeah

7. misty1212

so $f(-2)=\sqrt{-2+6}+2=\sqrt{4}+2=2+2=4$

8. misty1212

i.e if $$x=-2$$ then $$y=4$$ so $$(-2,4)$$ is on the graph

9. anonymous

oh I was right then? I was dying trying to graph this because it wasn't really exact but (-2, 4) was the closest.

11. misty1212

how did you graph it?q

12. anonymous

It's on paper so I can only describe it but it was exactly on the -4 just a little under.

13. anonymous

Your way gives me the exact thing though so that's nice.
