Beyond the Answer
To tackle the questions regarding the given insect population function
, let’s break it down:
(a) To determine the number of insects at
, we substitute
with 0 in the function:
(b) The growth rate of the insect population is represented by the coefficient of
in the exponent of the exponential function, which is
. This means the population grows at a rate of
per day.
© To graph the function, you can use any graphing utility (like Desmos or a graphing calculator). Plot
and observe how it rises exponentially.
(d) To find the population after 10 days, substitute
into the function:
Thus, the population after 10 days is approximately
insects.
(e) To find when the population reaches 720, set
:
Divide both sides by 600:
Taking the natural logarithm of both sides:
So, the population will reach 720 insects in about
days.
(f) To determine when the population will double, set
:
Taking the natural logarithm:
Hence, the insect population will double in about
days.
