Topic 9 Quadratic Equations

Is this a maximum or minimum?

• maximum

• minimum

• cannot be determined

• both

True or false:

Solutions, roots, and zeros are all the same thing.

• True

• False, because solutions and roots are the same but zeros are different.

• False, because zeros and roots are the same but solutions are different.

• False, they are all different

What is the arrow pointing at? How can you use this value?

• The arrow is pointing at the y-intercept. The x-value is the axis of symmetry and the y-value of this point is equivalent to the maximum/minimum.

• The arrow is pointing at the vertex. The y-value is the axis of symmetry.

• The arrow is pointing at the solution. The y value of this point is equivalent to the maximum and the x value is equivalent to the minimum

• The arrow is pointing at the vertex. The x-value is the axis of symmetry.
