no, you need to put a shaded circle on the y-axis at the point 1. the shaded dot to the far right should not be there. and you need to draw the the graph on the x-axis for x < -1 and x > 1

3. Hello, rmn!

You have to read what it says . . .

Did I do this right?...and any tips on graphing limits?

$f(x)\;=\;\begin{Bmatrix}x & -1 \leq x < 0,\;0 < x \leq 1 \\
1 & x = 0 \\
0 & x < -1,\;x > 1 \end{Bmatrix}$

When $x$ is on the invervals $[-1,\,0)$ and $(0,\,1]$
. . we have the line $y \,=\,x$
Code:
                  |
|       *
|     * :
|   *   :
-1       | *     :
- - + - - - o - - - + - - -
:     * |       1
:   *   |
: *     |
*       |

When $x = 0,\:f(0) = 1$
Code:
                  |
1*       *
|     * :
|   *   :
-1       | *     :
- - + - - - o - - - + - - -
:     * |       1
:   *   |
: *     |
*       |

When $x$ is on the intervals $(-\infty,\,-1)$ and $(1,\,\infty),\;f(x) = 0.$
Code:
                  |
*       *
|     * :
|   *   :
-1       | *     :
* * * * o - - - o - - - o * * * *
:     * |       1
:   *   |
: *     |
