Determine the points at which the function is discontinuous and state the domain using interval notation


Please help.

  1. Steve

    It is discontinuous where the denominator is zero, because division by zero is undefined.

    so, where is
    = 7(u+π)-u(u+π)
    = (7-u)(u+π)

    So the domain is all reals except those values.
