The cardinality of the union between two sets is given by
In fact, if an element is in both A and B, it is counted in both N(A) and N(B), so we're counting it twice. By subtracting the cardinality of the interserction, we're taking back one of these "extra-counted" element, and the count is correct. In your case, the numbers are
This means that the two sets cover, without repetitions, 43 of the 66 elements in the sets. So, there are
elements which are in neither A nor B
Answer:
Domain: All real numbers
Range:
Step-by-step explanation:
The domain is the set of all x values. The quadratic equation continue to operate over all x-values in both directions. The domain is all real numbers.
The range is the set of all y-values. Here the quadratic begins at -3 and continues in a downward direction forever. Then range is
