Question

Which graph best represents a quadratic function that has only one zero?

Answer 1

Answer:

B

Step-by-step explanation:

A has 2 it crosses the x axis 2x

B Has 1.

C has 2

D has none since it never touched the x axis

Answer 2

Option B is correct.

Quadratic function :

If the graph of quadratic function crosses x - axis at two points then that function has two zeros.

• If the graph of quadratic function crosses x - axis at only one point then that function has only one zero.

• If the graph of quadratic function do not crosses x - axis at any point then that function has no zeros.

• From given option, It is observed that option B graph crosses x- axis at only one point.

Therefore, Option B graph represent a quadratic function that has only one zero.
