Question

The number of fruit flies in a jar triples every week. The function f(x) = 5(3)x models the insect population after x weeks. To the nearest whole number, what will the population be after 4 weeks?

Answer 1

Answer:

405

Step-by-step explanation:

Considering the function:

$f(x) = 5(3)^x$

After 4 weeks, means $x=4$

$f(4) = 5(3)^4\\f(4) = 5(81)\\f(4) = 405$

What will the population be after 4 weeks?

405 insects
