Answer:
Domain is all real numbers or (negative infinity, positive infinity)
Step-by-step explanation:
Domain is all values of <em>x</em> (inputs) that will work with the function. Since a parabola has no limits for <em>x</em>, and all numbers work for <em>x</em>, then the domain can be any number. That leaves us with All Real Numbers as our answer.

Answer: ![\frac{4}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B15%7D)
Step-by-step explanation:
The number of seats in the first row= 8
Total number of seats in the classroom= ![8+10+12=30](https://tex.z-dn.net/?f=8%2B10%2B12%3D30)
The probability of the first student who enters the classroom will be assigned a seat in front row is given by:-
![P=\frac{\text{Number of seats in first row}}{\text{Total seats}}\\\Rightarrow\ P=\frac{8}{30}=\frac{4}{15}](https://tex.z-dn.net/?f=P%3D%5Cfrac%7B%5Ctext%7BNumber%20of%20seats%20in%20first%20row%7D%7D%7B%5Ctext%7BTotal%20seats%7D%7D%5C%5C%5CRightarrow%5C%20P%3D%5Cfrac%7B8%7D%7B30%7D%3D%5Cfrac%7B4%7D%7B15%7D)
Therefore, the probability of the first student who enters the classroom will be assigned a seat in front row is

We have to evaluate the unit rate for 1 Apple for $0.19.
The formula for unit rate is shown below.
![\text{Unit rate }= \frac{\text{Cost of the prodcut}}{\text{Number of units}}](https://tex.z-dn.net/?f=%5Ctext%7BUnit%20rate%20%7D%3D%20%5Cfrac%7B%5Ctext%7BCost%20of%20the%20prodcut%7D%7D%7B%5Ctext%7BNumber%20of%20units%7D%7D)
Now, we have been given the cost of the apple is $0.19 and the number of unit is 1. Hence, using the above mentioned formula, the unit rate is given by
![\text{Unit rate }= \frac{0.19}{1}\\ \\ \text{Unit rate }= 0.19](https://tex.z-dn.net/?f=%5Ctext%7BUnit%20rate%20%7D%3D%20%5Cfrac%7B0.19%7D%7B1%7D%5C%5C%0A%5C%5C%0A%5Ctext%7BUnit%20rate%20%7D%3D%200.19)
Therefore, the unit rate is 0.19 dollars per apple.
