Intervals of increase and decreaseIf you have a function and there's an asymptote at say -7, then when doing the intervals for increase decrease, would you do something like increasing from ( − ∞ , − 7 ) ∪ ( − 7 , wherever increase stops ) and not include the -7, or would the -7 be included

Intervals of increase and decreaseIf you have a function and there&#039;s an asymptote at say -7, then when doing the intervals for increase decrease, would you do something like increasing from   (  −  ∞  ,  −  7  )  ∪  (  −  7  ,  wherever increase stops  ) and not include the -7, or would the -7 be included

Explanation:The given interval does not include -7. It is a limit point.If you don&#039;t want to include −7 in the interval, then that is a way to express it.  (  −  ∞  ;  −  7  )  ∪  (  −  7  ;      x          max        ]    ≡    (  −  ∞  ;      x          m      a      x        ]  ∖  {  −  7  }

If you have a function and there's an asymptote at say -7, then when doing the intervals for increase decrease, would you do something like increasing from (-infty, -7) cup (-7,wherever increase stops) and not include the -7, or would the -7 be included.
