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