Use a table of values to graph the function ƒ(x) = x−−√. Choose the correct graph from the options below.

B

Step-by-step explanation:

The square root function's graph is graph (b). This makes logical sense, because, when taking the square root (the principal root in particular), a general rule is that both the input and the output must be positive. Moreover, if one were to create a table of values to find points on the graph of the function, each of the points can be found on graph (b).

x         y

1          1

4         2

9         3

16        4

Therefore graph (B) is the correct answer.
