.
Answer:
Second option {x | x > 7}
Step-by-step explanation:
We have the function

We know that the square root of a negative number has no solution in the real ones. Therefore the domain of this function is 
When applying the transformation:
we have a translation of the original function in 7 units to the right and 2 units to the top:

In the same way we must guarantee that 
Then
.
Therefore the domain of f(x) is {x | x > 7}
Answer: 75 students.
Step-by-step explanation:
In the data set we have a total of 10 + 8 + 7 + 5 = 30 students.
of those, 10 want to go to the park, the percentage is:
(10/30)*100% = 33.3%
Then, out of the 225, we can expect that a 33.3% (or 0.333 in decimal form) want to go to the park, this is:
N = 225*0.333% = 74.925
We can roud it up, and get N = 75
So Sally can expect that 75 students want to go to the park
