Question

As time, t, passes, the concentration of organisms in a seawater sample is modeled by the function:

C(t)=0.80(1.2)^t

Which of the following statements is supported by the behavior of C(t)?

According to C(t), the concentration of organisms will decrease over time.

According to c(t), the concentration of organisms will remain the same

No generalizations can be made because c(t) will both increases and decreases

over time According to C(t), the concentration of organisms will increase over time.

Answer 1

According to C(t), the concentration of organisms will increase over time.

The growth rate is 20% as indicated by 1.2

Exponential functions of the form y = a(b)^c are always increasing or always decreasing
