3x2 + 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 f (x)=–x+12. Hence, the result is as follows.
limx›-3+ f(x) = -(-3) + 12 = 3 + 12 = 15
