    (-7, 0) are the coordinates of the function.

    Step-by-step explanation:

    The given function is f (x) = (x²+3x-28) / (x+7).

    We have to find the coordinates of hole of the given function.

    To find the coordinates of the hole we will find the factors of the numerator first.

    x² + 3x - 28 = x² + 7x - 4x - 28

    = x (x + 7) - 4 (x + 7)

    = (x + 7) (x - 4)

    Now we know that factor (x + 7) is common as denominator therefore these factors will get cancelled.

    Therefore x + 7 = 0

    Or x = - 7

    and for x = - 7 the value of y = (x²+3x-28) / (x+7) = 0

    Therefore the coordinates of the hole of the given function is (-7, 0).

    The coordinates are (-7, - 11) actually. I took the test already.

    Good luck!
