Limit x menuju 3 dari 9 - ×^2 dibagi 4- akar x^2 + 7 adalah...

lim. ( 9 - X² ) ..( 4 + √x² - 7 )
x→3 ( ------------ ) ( ----------------- )
(4 - √x² +7 ) (4 + √x² - 7 )

lim. (9 - X²) (4 + x - 7 )
x→3 (---------) (------------)
(4 - x +7) (4 + x - 7)

lim. 36 - 9x-63-4x²+x^3 -7x²
x→3. ------------------------------------
16+4x-28-4x-x²-7x+28+7x-49

lim x^3 - 11x² - 9x - 99
x→3. -----------------------------
x² - 33

lim. 3^3 - 11(3²) - 9(3) -99
x→3 -------------------------------
3^3 - 33

9 - 99 - 27 -99
= ------------------------
9 - 33

= - 216 / -24

= 9
