At 10 : 00 am there were 2 , 000 bacteria present in the culture. at noon, the number of bacteria grew to 2, 500 . how many bacteria will there be at midnight?

At 10, there were 2000at 12, there were 2500..
that means in 2 hrs, they increased by 500that means they increase at a rate of 250 per hr

f(x) = 250h + 2000midnight is 12 hrs from 10 a.mso h = 12
f(12) = 250(12) + 2000
f(12) = 3000 + 2000
f(12) = 5000 <===
