To graph the function using a table of values. The function is:


f(x)=\sqrt[]{x}

Since the root is even, because it is a square root, there is no Real values for


x<0

This already indicates that the probable correct alternative is C, however let's make the table to make sure.

The best way is to get x values that will easily get was f(x) values. Let's pick x = 0, x = 1 and x = 4:


\begin{gathered} f(0)=\sqrt[]{0}=0 \\ f(1)=\sqrt[]{1}=1 \\ f(4)=\sqrt[]{4}=2 \end{gathered}

So, the points (0,0), (1,1) and (4,2) should be in the line. This exclude alternatives A, B and D. In C we can see these points:

So, the graph of the given function is the one showed in option C
