Answer:
Option b is correct
.
Step-by-step explanation:
Domain is the set of all possible values of x where function is defined.
Given the function:

To find the domain of the given function:
Exclude the values of x, for which function is not defined
Set denominator = 0

By zero product property;
and 
⇒x = 0 and 
⇒x = 0 and 
Therefore, the domain of the given function is:

Answer:
In interval form range is [-2,16]
Step-by-step explanation:
Here we can see that given equation is circle
whose center is (5,7 ) and radius is 8 ,
Range of the circle is actually values of y it changes from
if (h,k) is the center and r is the radius of circle then range is given by
k-r ≤y ≤ k+r
here in the question k = 7 and r =9
therefore range is
7-9 ≤y ≤ 7+9
-2 ≤y ≤ 16
In interval form [-2,16]
B. Just find the percentage to see if it is correct

It equals about .3356, but multiply it by 100 to get its percentage which is about 34%. So yes it is correct.
C.

Simplified would be a ratio of

So they would be incorrect
