Question

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

Answer 1

It's B on edge.

Answer 2

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).
