Answer:
There are no solutions to this equation because we will end up in 0=0 or if we do other methods, you will get something = 0
Hope it helps :)
The mathematical formula to solve this is :
f(n)= f1 + (n-1)d
We have:f(n)= 11 + (n-1)-4
f(n)= 11 -4n +4
f(n)=15 -4n
The right answer is D.
Answer:

62
Step-by-step explanation:
For this case we have the following fusions:

We must find 
By definition:

The domain of the function will be given by all the values for which the function is defined, that is, all real numbers except zero.
Answer:
(-∞, 0) U (0,∞)
