1. ## Need help please Algebra 2 questions

1). Graph the function of y=square root of x-2 end of square root +5 which point lies on the graph?
2). y= square root of x+6 end of square root +2 which point lies on the graph?
Thank you!!

Thank you!!
just guessing here ... is this what you mean?

$\displaystyle y = \sqrt{x-2} + 5$

3. yes, thats what I mean

4. the graph of $\displaystyle y = \sqrt{x-2} + 5$ is a transformation of the parent function $\displaystyle y = \sqrt{x}$ ... do you understand how the parent graph changes with each transformation?

$\displaystyle \displystyle y = \sqrt{x-2}+5$ lies on which graph?

6. You have to graph it then see which point lies on the graph, but I don't know how.

did you know that you can sub in the x-coordinate and see if it works out to the y-coordinate?

specifically ... (I'm making this up since you provided no information about specific points in your OP) ... say you need to check the point $\displaystyle (2,5)$

$\displaystyle y = \sqrt{x-2} + 5$

sub in $\displaystyle x = 2$

$\displaystyle y = \sqrt{2-2} + 5 = 0 + 5 = 5$

now you can say the point $\displaystyle (2,5)$ lies on the curve $\displaystyle y = \sqrt{x-2} + 5$

8. Many points lie on this graph, how many are you after?

Or are you trying to find the domain and range?

9. just two points didn't say domain and range
