Question

Monique has 3 eggs and needs to buy more. A store has 6 dozens of eggs. Monique needs to buy at least 2 dozen. The number of eggs Monique will have after purchasing x dozen is represented by a function.

f(x)=12x+3
What is the practical domain of the function?

All integers from 2 to 6, inclusive.
{27, 39, 51, 63, 75}
All real numbers.
All real numbers from 2 to 6, inclusive.

Answer 1

All integers from 2 to six inclusive.I took the same test.

Answer 2

Let

x--------> the number of dozen of eggs

f(x)-------> the number of eggs

we know that

`f(x)=12x+3`

The domain of the function is the amount of dozens of eggs that Monica can buy

The domain is the interval------->
`[2,3,4,5,6]`

All integers from
`2` to
`6`, inclusive

The range is the interval------->
`[27, 39, 51, 63, 75]`

therefore

the answer is the option

All integers from
`2` to
`6`, inclusive
