Brainliest if right!
which of the flowing graphs is increasing only when x< 0?

Let's analyze each graph.

Graph W is actually decreasing when x<0, so it is incorrect.

Graph X increases when x<0 and not when x≥0, so that makes it a possible answer.

Graph Y decreases when x<0, so it is incorrect.

Graph Z increases when x<0, but it is also increasing when x≥0, so Graph Z is incorrect.

Graph X is the only correct answer.

Have an awesome day! :)
