A bacteria culture starts with 900 bacteria and the population doubles every 4 hours. Find an expression for the number of bacteria after t hours.
Sense there are 900 bacteria and every 4 hours it doubles, you would multiply for by x to get 34 sense that is a composite number, you would then subtract it from 900. Then just do 900-34+t-17. And there ya hav it. Oh! don't forget to right t as an expolentontion. (Delperdination)
