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

{27, 39, 51, 63, 75}{27, 39, 51, 63, 75}

All real numbers from 2 to 6, inclusive.

All integers from 2 to 6, inclusive.

All real numbers.

Answer 1

Answer 2

she needs at least 2 but the store has 6

so domain is all integers from 2 to 6

it is not b, because real number include pi and 2/3. you can't buy pi dozen eggs

answer is c
