    What are the zeros in the function  ? - ProProfs

    What are the zeros in the function  ?

    • {-11, -5}

    • {17}s

    • 9-3 And 9-4: Solving Quadratic Equations By Graphing And By Factoring - Quiz

    • {5, 11}

    Correct Answer
    A. {5, 11}
    Explanation
    The zeros of a function are the values of x for which the function equals zero. In this case, the zeros of the function are 5 and 11, as these are the values of x that make the function equal to zero.

    Find the x-intercepts in the function  - ProProfs

    Find the x-intercepts in the function 

    • {7, 8}

    • {-7, -8}

    • {-7, 8}

    • {7, -8}

    Correct Answer
    A. {7, 8}
    Explanation
    The x-intercepts of a function are the points where the graph of the function intersects the x-axis. In this case, the x-intercepts are given as {7, 8}. This means that the function crosses the x-axis at the points (7, 0) and (8, 0).

    • 9-3 And 9-4: Solving Quadratic Equations By Graphing And By Factoring - Quiz

    • No Solution

    Correct Answer
    A. No Solution
    Explanation
    The given equation is -8 = 8, which is not true. Therefore, there is no solution to this equation.

    One root of the quadratic equation whose related function is graphed lies between which consecutive integers? - ProProfs

    One root of the quadratic equation whose related function is graphed lies between which consecutive integers?

    • -4 and -3

    • 0 and 1

    • -5 and -4

    • -3 and -2

    Correct Answer
    A. -4 and -3
    Explanation
    The correct answer is -4 and -3 because the graph of a quadratic function intersects the x-axis at the x-coordinate(s) of its roots. Since the question states that one root lies between -4 and -3, it means that the graph intersects the x-axis between these two consecutive integers.
