Answer:

When x = 0 and x = 6 then function is undefined.

Step-by-step explanation:

When the denominator of the function is zero, then the function  is undefined.

  x² - 6x = 0

x(x - 6)   = 0

x = 0  or x - 6 = 0

                   x = 6

When x = 0 or x = 6, the denominator will become zero.

x = 0  ⇒ x² - 6x = 0   and

x = 6 ⇒  x² - 6x = 6² - 6*6

                          = 36 -36

                           = 0

When x = 0 and x = 6 then function is undefined.
