    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

    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 \\<br />
1 & x = 0 \\<br />
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
              :   *   |
              : *     |
              *       |
