In this question, we have to write the set of points from -6 to 3 but excluding -2 and 3 as a union of intervals .
For union, we use U.
For the points that we have to exclude , we put parenthesis on there side that is ().
Therefore the required interval form is
As we see that () are used with -2 and 3 . And that's the required interval form .
The given term is:
Since here, the numerator i.e.
cannot be factorized.
SO, the only excluded value is found on the basis of the denominator. The denominator should not be equal to 0, otherwise, the fraction will turn out to be zero.
SO, if y
-4, then denominator will not be zero.
Therefore, the excluded value is -4
If (2 - 3) + (x + y) = 6, x + y = 4 + 3
*how to solve*
First simplify:
-1 + (x + y) = 6
Add 1 to each side
x + y = 7
Chose the answer that adds up to 7 (aka x + y = 4 + 3
