Answer:
2 and 4
Step-by-step explanation:
the number of years after 2000 cannot be negative, nut it can be 0 since you can say that it is the year 2000
so an inequality would be t is greater than or equal to 0, and you can write this as t [tex]\geq[/tex] 0
4 is just saying what t [tex]\geq[/tex] 0 in word form: t is greater than or equal to 0
