A scientist is observing bacterial population growth on a microscope slide. Initially there are 72 organisms. The scientist notes that the population triples every hour. What function, P(t), can she use to describe the changes in population as a function of time, in hours, t? Your equation should start with P(t)=

Answer:

[tex]P(t)=72(3)^t[/tex]

Step-by-step explanation:

We have to find an equation of the form [tex]f(x)=ab^x[/tex], where a is the initial value, b is the rate, and x is the time.

Here, the initial amount if 72, so a = 72. We also know that the population triples every hour, which means b = 3. Plug these in:

[tex]P(t)=ab^t[/tex]

[tex]P(t)=72(3)^t[/tex]
