Question

The number of solution(s) of $y=-|\log x|$ and $y=1,$ is

• A. $0$
• B. $1$
• C. $2$
• D. $3$

Answer 1

The correct option is A $0$

Curve of $y=\log x$ is


Now, curve of $y=|\log x|$ is


We get $y=-|\log x|$ by inverting the graph of $y=|\log x|$ with respect to $x-$ axis.


As $y=-|\log x|$ and $y=1$ does not intersect, hence number of solutions is $0.$
