How do you write 4000000+30000+800+20+5 in standard form

You could write " 4,030,825 " .

Or you could say "Four million thirty thousand eight hundred twenty-five."

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
