Match the following. Given A = {1, 2, 3, 4, 5} B = {2, 4, 6} C = {1, 3, 5}

1. A ∪ (B ∩ C)
{1, 3, 5}
2. A ∩ C
{2, 4}
3. A ∩ B
null, or empty set
4. A ∩ (B ∩ C)
{1, 2, 3, 4, 5}
5. B ∪ C

step-by-step explanation:

the orientation of the parabolas can easily be found by analysing the power of x and y and their signs. if x is squared , parabola opens up and also if its coefficient is negative it opens down. if y is squared , the parabola opens right and also if its coefficient is negative it opens left. however in order to do the above analysis our equation must be in standard form .

our parabola is

which is not standard form of any parabola . hence we square on both hand side and convert it into standard form.

hence we see that x is squared and its coefficient is non negative . there for it opens up.
