5. Tentukan: a. lim (r + 3x + 1) . *--2 - 1 b. lim -3x2 + x-2
![]()
Penjelasan dengan langkah-langkah:
Limit
-
substitusi nilai r dan x
A. Lim r->2 (r + 3x + 1)
L = (r + 3x + 1)
L = (2 + 3(2) + 1)
L = (2 + 6 + 1)
L = 9
B. Lim x->3 (x² + x - 2)
L = (x² + x - 2)
L = (3² + 3 - 2)
L = (9 + 3 - 2)
L = 10
