Question

The function `f( x) = 10,000-1,500x` can be used to predict the number of termites in an area `x` days after the area has been treated. How many termites are predicted in the area after 5 days?

Answer 1

`2500`

Explanation:

Here, because we want to know the number after 5 days, and `x` is the number of days, we have to find the value of `f(5)`

Let `x=5`

`f(5)=10000-1500(5)`

`=10000-7500`

`=2500`
