    y. It means the maximum value of the function is 5. It is possible if the vertex of a downward parabola is in the form of (h, 5). Answer:

    Step-by-step explanation:Answer:

    The correct option is 2.

    Step-by-step explanation:

    The range of a parabola is y ≤ 5.

    It means the maximum value of the function is 5. It is possible if the vertex of a downward parabola is in the form of (h, 5).

    The vertex form of a parabola is

    Where, (h, k) is vertex and a is a constant.

    If a0, then f (x) is an upward parabola.

    In option 1,

    It is an upward parabola with vertex (4,5), therefore the range of the function is y ≥ 5. Option 1 is incorrect.

    In option 2,

    It is a downward parabola with vertex (4,5), therefore the range of the function is y. Option 2 is correct.

    In option 3,

    It is an upward parabola with vertex (5,4), therefore the range of the function is y. Option 3 is incorrect.

    In option 4,

    It is a downward parabola with vertex (5,4), therefore the range of the function is y ≤ 4. Option 4 is incorrect.
