Answer: y = sqrt x
Step-by-step explanation:
In order to draw the graph of this function you will need to identify some of the values.
If x=0, then y = sqrt 0.
If x=1, then y = sqrt 1.
If x=2, then y = sqrt 2.
(This repeats.. you get the idea)
Plot these points and draw a curve through them. Your answer should look just like the graph in your question.
