Question

Which is the graph of y=log(-x)

Answer 1

Answer:

Step-by-step explanation:

The given function is,

$y=\log(-x)$

The parent function of it is,

$y=\log(x)$

In $y=\log(x)$ graph y-axis is an asymptote (vertical) , so never crosses the y-axis. Hence no y intercept. And x intercept of $y=\log(x)$ is x=1.

The sign of x is changed in the given function $y=\log(-x)$ as compared to its parent function $y=\log(x)$

While reflecting over y axis or x=0 line, only the sign of x changes.

So graph of $y=\log(-x)$ is the reflection of $y=\log(x)$ over y axis. Hence it has no y intercepts, x intercept at x= -1 and y-axis as asymptote (vertical).
