Answer:
Positive
Step-by-step explanation:
refrigerator is 210, so it positive.
Step-by-step explanation:
please provide formula
If a function is defined as

where both
are continuous functions, then
is also continuous where defined, i.e. where 
So, in your case, this function is continous everywhere, except where

To solve this equation, we can use the formula 
It means that, if the leading terms is 1, then the x coefficient is the opposite of the sum of the roots, and the constant term is the product of the roots.
So, we're looking for two terms whose sum is 7, and whose product is 12. These numbers are easily found to be 3 and 4.
So, this function is continuous for every real number different than 3 or 4.
Answer:
w is greater than or equal to 358
1
The variable in this case is v, and no coefficient is given, so it can be assumed to be 1.
