403,892 round to the nearest thousand

404,000

Step-by-step explanation:

you round high if the number is above or the same as 5/50/500/5,000 etc...

If the number is low than 5 and etc u round low.

403,892

round to thousands, so 3,892. 3,892  would be rounded to 4,000 because 3,892 is closer to 4,000 than 2,000. or like the 892 is higher than 500, (if it were to be 500 tho u would still round high btw) Get it?

i think is g(1)=-1.

hope that i can
