A sideways opening parabola is in the form
, so we know from the process of elimination that it will either be b or c. Next we have to realize that if the parabola opens to the left it is a negative parabola, just like if a parabola opens upside down it is a negative parabola. So the one that has the negative out front is b.

Step-by-step explanation:
Patrick's statement is incorrect.
Explanation:
Crackers come in package of = 24
Cheese slices come in package of = 18
As given, Andy wants one cheese slice for each cracker so we will find the least common multiple of 24 and 18.
The L.C.M is 72.
So, Andy needs 72 crackers and 72 cheese slices.
Number of cracker packages needed=
Number of cheese slice packages needed=
Hence, Patrick's statement is incorrect. Andy needs 3 packages of crackers and 4 packages of cheese slices to make them even.
