Bantu ya kak. plus soap matematika klas 11

pakai turunan
16.
-½(1 / √(x+1))
------------------
1
masukan x = 3
-½(1 / √(3+1))
= -½(1 / √4)
= -½(1 / 2)
= -1/4

17.
3
-----------------------------------------
½(1 / √(9+x)) - (-½)(1 / √(9 - x))
masukan x = 0
3
---------------------------------------------
½(1 / √9) + ½(1 / √9)

3
----------------------
½(1/3) + ½(1/3)

3
------------------
1/6 + 1/6

3
--------
2/6

3
------
1/3

= 9
