diketahui f(x)=3log(x+11)tentukan Nilai dari a.f(-8) b.f(-2) c.f(16) d.f(70)

kalau nggak salah jawabannya tu A

f(x) = 3log (x +11)
f (-8) = 3log (-8+11)
= 3log 3
= 1
b) f (-2) = 3log (-2+11)
=3log 9
= 3log 3^2
= 2
c) f (16) = 3log (16+11)
= 3log 27
= 3log 3^3
= 3
d) f (70) = 3log (70+11)
= 3log 81
= 3log 3^4
= 4
