Let $f(x)=%0$. To draw the graph of $f$, first choose some convenient values of $x$ (we have chosen $x = -2, -1, 0, 1, 2$). Then, calculate $f(x)$ for each value of $x:$
$x\ $ \t $-2$ \t $-1$ \t $0$ \t $1$ \t $2$
\\ $f(x) = %0$ \t BOX \t BOX \t BOX \t BOX \t BOX
The graph of the function $f$
consists of all possible points $(x, f(x))$ for $x$ in the domain of $f$. The above table gives us a few points on the graph: Use the values of $f(x)$ in the table as values of $y$ and then plot the resulting points $(x,y)$. 1.
Adjust the points plotted below in this way.2.
Then press "Check" to see wheher they are correctly plotted.3.
To obtain the curve suggested by these points, press "Connect the points".
