Third Option
Step-by-step explanation:
We know that the function
is defined as
. Since the denominator is
then we know that
when 
We also know that the division by 0 is not defined. Therefore, the limit of
when "x" tends to
is infinite.
The function
is the inverse of
By definition, if we have a function f(x), its domain will be equal to the range of its inverse function
. If
, then 
This also happens for the function 
If when
then when 
Then, the answer is:

G>=5, so anything above or equal to 5 would count. So, you could use 5, 6, 7.

Step-by-step explanation:
The circumference formula is
or
.
But since we're given the diameter, 170,000, all we have to do is multiply it by
.

The square root of 225 is 15. I hope that helped!
