                                       3x+ 5,   x < -3               

If f : R - {-3} › R, f (x ) = ?-x + 12,   x > -3

then which of the following is the  the value of limx›-3 f(x)? 
  


3

-6

9

-12

15


Yanıt Açıklaması:

Because x approaches -3 from the right side x is more than -3 and for x > -3, f is given by the rule (x)=–x+12. Hence, the result is as follows. 

limx›-3 f(x) = -(-3) + 12 = 3 + 12 = 15
