Like 0?

Exclude values of x where the division is undefined. So,
y = -2/5x+40
as written, exclude x=0
Assuming the usual carelessness with parentheses,
y = -2/(5x+40)
exclude x = -8

There are no excluded values in this function. The variable x can take any real value.

No problem, please provide the correct function so I can help you.

Yes, zero is a possible value for x. There are no values that would make the denominator of the fraction zero and create an undefined function.

Yes, that's correct. In the second equation, the denominator is 5x+40, so x=-8 would make the denominator zero and create an undefined function. Therefore, x=-8 is an excluded value. For the first equation, x=0 does not create an undefined function, but it is still important to mention that zero is not in the domain of the original function due to the presence of the division.
