Question

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

Answer 1

Kalau nggak salah jawabannya tu A

Answer 2

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
