Okay so basically domain =input and range =output. you can never have a negative number underneath the square root sign because it will make the answer imaginary (i), unless you are on that concept. Therefore the range is any number greater than 0. -> all real numbers greater than or = 0
for the range if you input 0 as x you will get -5, so any number you input after 0 will be greater than -5. so range is all real numbers greater than or equal to -5.
1. is 8
2. is 4
Subtract them by the percentage
It would be 20 because the highest number is 25
Answer:
240 people are going on the field trip.
Step-by-step explanation:
As per the statement each school bus is going on the field trip it holds 36 students and 4 adults.
Then;
total number of people in each bus = 36 students + 4 adults = 40
Also, they are having 6 filled buses on the filed trip so,
total number of people on the filed trip is equal to the 6 times of each number of people in each bus
i.e,
Total number of people on the filed trip =
Therefore, 240 people are going on the field trip.
The domain is {x|x greater than -2}
OR
(infinity, -2]
