8. Which ofthe following is the graph ofthe function f(x)=-ln(x)? A B -g- 6 4-6 8 _ 6 i4_-2-2 6-8 -8-6-4-2- 2 -6 C D -8-6-4-2 -4 -6 -8 2 48642 2-4-6-8 68 8642 | -2-4-6-8 2 2 8642 68 8642 2468

Solution

f(x) = -ln (x)

since for log functions,

Domain = x > 0

So option A and C are wrong.

f(10) = -ln 10 and we know that

ln 10 > 0

So,

f(10) < 0

So option D is wrong.

Correct option will be B.
