Work Step by Step
Sketching a graph y=f(x):
1. Select several x-values from the domain of f, and calculate f(x) for each x-value.
(Make a table of function values)
2. Plot the points (x,f(x)) obtained.
3. Join the points with a smooth curve.
$\sqrt{x}$ is defined for nonnegative x.
Table: $\left[\begin{array}{lll}
x & \sqrt{x} & \\
0 & 0 & (0,0)\\
1 & 1 & (1,1)\\
4 & 2 & (4,2)\\
9 & 3 & (9,3)
\end{array}\right]$
