• Yes
• No

Which inequality is shown?

(2,2) is a solution to the inequality 2x-6y>x²+4x-8

• True
• False

Which inequality is represented by the graph?

Hint: write in Vertex Form nothing else changed

Which inequality is represented by the graph?

• y > -(x - 4)² + 1

• y > -(x - 1)² + 4

• y < (x - 4)² + 1

• y > (x + 4)² + 1

• y ≤ (x - 3)² + 3
• y < (x + 3)² - 3
• y < (x - 3)² - 3
• y ≤ (x + 3)² - 3

Standard form of a quadratic equation

A parabola is upside-down when a is:

• negative
• positive
• 0
• infinite

Does this parabola have a minimum or maximum and what is its value?

Use the picture to find the vertex and axis of symmetry.
