Answer:
[ where
is number of months]
Step-by-step explanation:
Pool pass cost for first month =$30
Pool pass cost after first month = $15 for each month
The total amount charged by the pool can be expressed as a function where
represents the number of months.
This can be simplified by using distribution.
Take 15 as greatest common factor.
∴
For
∴ Amount charged by pool for 12 months = $195
When leading coefficient is 1 , the root will be an integer for g(x) = 0
Option 4 is the right answer.
<h3>What is a Polynomial Function ?</h3>Functions of independent variable in which the variable can appear more than once with different powers.
Let this represents the polynomial function
where
Then the according to rational root theorem ,
The root of the function is given by
So when leading coefficient is 1 , the root will be an integer for g(x) = 0
Option 4 is the right answer.
