EXPONENTIAL EQUATIONS & FUNCTIONS
A culture of bacteria doubles in weight approximately every 2.5 hours. The number of bacteria after t hours later can be approximated by 𝑁(𝑡) = 175(2.5)t
a) How many bacteria would there be initially (𝑡 = 0)?
b) Find 𝑁(4). What does this number tell you in terms of this problem?
