tolong dibantu dengan benar. yang no 4 (yang selain itu ngga usah dikerjain)mksh

jawab

y = '¹/³log (ax + b)
(ax +b) = (1/3)^y

melalui
(2,0)  → a(2) + b = (1/3)^0
2a + b = 1

(10, -2) → a(10) + b = (1/3)⁻²
10a + b = 3²
10a + b  = 9

2a + b = 1
10a + b = 9..||(-)
-8a = - 8
a = 1

b = 1 - 2a
b = 1 - 2(1)
b = -1

y = ¹/³log(ax+b)
y = ¹/³log (x - 1)
y =  ³log (x +3)⁻¹
y = ³log{1/(x+3)}
