Question

Which of the following graphs could represent a quadratic function

Answer 1

Option: A is the correct answer.

A. Graph A

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
