    there are 2 zeros

    There are two zeros placed in the graph when there is only suppposed to be one.

    The equation was not placed at the of side of the curve line.

    1.Points are not marked with crosses.
    2.Line is extended.

    The graphs has 2 points of origin (0) and the line is not symmetrical.

    1.No "x" to mark the points.
    2.The curve is extended.

    There are two 'O's at the origin. There is no scale. The graph is extended.

    1. NO 'x' to mark points
    2. Line extended
    3. 2 zeros

    There's an extension in the curve drawn.

    There's no equation written on the graph.

    There're no crosses along the curve drawn.

    The curve drawn is not on -4 and 2 but instead, it's -4.4 and 2.2.

    The graph is not plotted with crosses.The equation is not written in the graph.The line of symmetry is not drawn.The curve is extended.There is no scale .

    The line was extended beyond the given points.

    1)the curve exceeds -4 which it should not .
    2)the bottom should not eceed -1.

    Rebecca Yiu:
    The values of x supposed to -4,-3,-2,-1,0,1,2
    but the curve had values that are -5,-6, 4,5

    the are 2 zeros. no crosses. the graph is extended

    The graph has been extended.
    In quadratic graphs, there should be no extension.

    The line are extended past -4 and 2. This is incorrect because the range of values given stop at -4 and 2. There is no equation on the graph.

    1. Lines at both ends are extended which are not supposed to be there.

    2. There are no crosses used to mark the points on the graph.

    3. There are no table of values.

    4. There is no equation in the graph.

    There are two zeros on the graph, no line of symmetry and table of values.

    I think the line is extended unecessarily when the table value is only until 2

    The curve is longer than -4 and 2.

    The curve has not touched -4 and 2 on the x- axis and there should be no extensions.

  23. Nooranah and AfifahMarch 30, 2009 at 7:12 PM

    the line goes beyond -4 (it's extended)

    No crosses on the line

    There should only be one 0

    The points on the graph does not satisfy the values on the table.
    There is not supposed to have any extensions as the x-values are to be strictly followed so that the curve can be more accurate.

    The graph is incomplete as the graph does not use and show the full range of table of values. It stops at x=1 but the question states the range till point number 2 for x.

    1. The extra values/space should not be used to be extended.
