Which of the following graphs could represent a quadratic function

Option: A is the correct answer.

             A.  Graph A

Step-by-step explanation:A quartic function is a function whose degree is 4 i.e. even.We know that for any even degree function the end behavior of the graph is in the same direction i.e. when x tends to infinity and minus infinity then the function goes in the same direction.And for any odd degree function the end behavior of the graph goes in the opposite direction.

Among the given graphs Graph A is such that both the ends of the graph goes in the same direction while in other they goes in opposite direction.

            Hence, the correct answer is:

                     Graph A
