Can college (Cal State La) revoke admissions?

I got admitted to csula. Okay I got my report card in pre-cal 1st semester I passed and 2nd I got a D. I was told that I have to keep atleast a 2.0. Okay my gpa is higher than that but can they revoke me? On my whole transcript I only have 2 D's counting this one. What do you think?
