I have this cube:

When I mirror it around the x-axis I get this:

but I want this, so that the object is mirrored and duplicated:

Currently, I can do that by copy-pasting the cube then mirroring the duplicate cube (leaving the original cube in place), but it feels like there should be a better way.
How do I mirror an object such that it is duplicated, leaving the original in place?
