Question

Dengan menggunakan strategi, tentukan nilai limit fungsi berikut

Answer 1

A. lim      x²+2x-3
   x-> 1   -----------
              2x - 2
lim     (x -1) (x+3)
x ->1   ---------------
         2 (x-1)
lim    (x+3)
x->1  ------
           2
= 1 + 3
   ------
     2
= 4/2 = 2

Answer 2

B. (x^3)-2x^2
--------------- lim(x-->2)
(x^2)-4

=(3x^2)-4x
--------------
2x
= (3(2)^2) - 4(2)
---------------------
2(2)
=3.4 - 8 = 12-8/4 = 4/4 = 1
---------
4
