Answer
The graph of the given function $f(x)=x$ is shown below:
Work Step by Step
Create a table of values by assinging values to $x$ then solving for the corresponding value of $y$ for each $x$:
\begin{array}{ccc}
&x &y &(x, y)\\
&0 &0 &(0, 0)\\
&1 &1 &(1,1)\\
&-1 &-1 &(-1,-1)\\
&2 &2 &(2,2)\\
&-2 &-2 &(-2,-2)\\
\end{array}
Plot the points then connect them using a line.
Refer to the graph above.
