To find the domain, you first need to find what x values will result in an imaginary number. To find this, solve the inequality -13-x >(or equal to)0. This comes out to x<(or equal to) -13. This means that’s the domain is [-13, negative infinity).
The number of students that are expected to carry a backpack is = 378
<h3>Calculation of total number of students</h3>
The total number of students in the assembly= 648
The number of students that enters the gym =12
