Does anyone know why this plot looks funny between 0 and 1 ? The same will happen if I try to plot the cube root function. Please advise. I am trying to avoid using pgfplots package.

Because your sample is not large enough: by default it is 25 points. With a sample of 200 points, this works.
Edit: Modification of the sample. Many thanks to Skillmon for having the idea to modify the sample and to @marmot for giving a simple and effective example.
Your foreach loops do not need to have two variables. Only one is enough, for the displayed text to be smaller, there is the key font=scriptsize.
Edit 2:
And to avoid repeating this for each node, just do it with every node/.style=font=scriptsize to overwrite the pre-existing style or every node/append style=font=scriptsize to simply add this style to the pre-existing style without overwriting it.

I'd suggest raising the number of samples only in the interval [0,1] and not on the rest. This way one could use less samples (better performance). The gradient isn't changing much on the interval [1,10], so one doesn't need that many.

Just split the plot in two parts, likedraw[domain=0:1, samples=50, smooth, variable=x] plot (x,(x)^.5); draw[domain=1:10, smooth, variable=x] plot (x,(x)^.5);. By the way, you're not usingpgfplotshere, but TikZ and its plot capabilities (pgfplotsis another package) :)

@Andre' , Thanks and In your opinion is there advantage using pgfplots instead? For some reason I want to do all my plotting as in the example above. Again Thanks!

Just split the plot in two parts, likedraw[domain=0:1, samples=50, smooth, variable=x] plot (x,(x)^.5); draw[domain=1:10, smooth, variable=x] plot (x,(x)^.5);. By the way, you're not usingpgfplotshere, but TikZ and its plot capabilities (pgfplotsis another package) :)

Because your sample is not large enough: by default it is 25 points. With a sample of 200 points, this works.
Edit: Modification of the sample. Many thanks to Skillmon for having the idea to modify the sample and to @marmot for giving a simple and effective example.
Your foreach loops do not need to have two variables. Only one is enough, for the displayed text to be smaller, there is the key font=scriptsize.
Edit 2:
And to avoid repeating this for each node, just do it with every node/.style=font=scriptsize to overwrite the pre-existing style or every node/append style=font=scriptsize to simply add this style to the pre-existing style without overwriting it.

I'd suggest raising the number of samples only in the interval [0,1] and not on the rest. This way one could use less samples (better performance). The gradient isn't changing much on the interval [1,10], so one doesn't need that many.

@Skillmon It's a good idea, but since I'm starting with pgfplots, I don't know how to do it. Write an answer explaining how to do it!

TikZ loads the
pgfpackage as it builds upon that.– Skillmon

I suppose I mean without using pgfplots. What is the advantage? Also I will try to rewrite this function in terms of logarithms to see if that makes a difference.

A much, much simpler solution without increasing sampling points is
draw[domain=0:3.162278,smooth,variable=x,blue,thick,->] plot (x^2,x);I always find re-parameterizing the function produces better looking results.– Ruixi Zhang
