Question

please help me
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)?

A)According to C(t), the concentration of organisms will decrease over time.
B)According to C(t), the concentration of organisms will increase over time.
C)No generalizations can be made because C(t) will both increase and decrease over time.
D)According to C(t), the concentration of organisms will remain the same.

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
