You (male singular) - הצג
You (female singular) - הציגי
You (male plural) - הציגו
You (female plural) - הצגנה (But it's rarely used, people these days use the male plural instead)
Also I must add and say, these days people don't use the imperative as they used to.
You'll hear a lot of times people using the present tense to express the imperative, it's not correct, but it's very common.
