Question

If a projectile

launched horizontally on the x axis is the displacement increase or decrease?

Answer 1

To answer in your terms it would increase.

Step-by-step explanation:

the displacement of an object "increases" as it moves away from its initial start point. So the further away that the object ends in comparison to where is started, would determine how large the displacement is. But typically I havent heard of displacement increasing or decreasing, the object is either displaced or it isnt.
