Can you please add a picture of the problem or type all the measurements and information?
For this case, we must indicate which of the given functions is not defined for
By definition, we know that:
has a domain from 0 to infinity.
Adding or removing numbers to the variable within the root implies a translation of the function vertically or horizontally. For it to be defined, the term within the root must be positive.
Thus, we observe that:
is not defined, the term inside the root is negative when
.
While
if it is defined for 
, your domain is given by all real numbers.
Adding or removing numbers to the variable within the root implies a translation of the function vertically or horizontally. In the same way, its domain will be given by the real numbers, independently of the sign of the term inside the root.
So, we have:
with x = 0:
is defined.
with x = 0:
in the same way is defined.
Answer:

Option b
Answer:
(3, 6)
yw
Step-by-step explanation:
Answer:
The real distance would be 16
Step-by-step explanation:
If the scale is 1/2, that means each distance on the map is half of what the real distance is. So 8 x 2 =16.
Answer:
-3
Step-by-step explanation:
Because slope is rise over run.
Rise = -3
Run = 1
Rise/Run = -3/1 = -3
