Quadratic Functions Vertex from Standard Form

Determine the solutions of the graph:

• No Solutions

• (-3, 0) and (-1, 0)

• Infinity Many Solutions

• (-1, 0)

What do we call the highest or lowest point of a quadratic?

• parabola

• vertex

• graph

• point

• A
• B
• C
• D

• A
• B
• C
• D

If given the equation
y = 3(x + 5)² - 4,
what is the vertex of the parabola?

• (5, -4)

• (-5, -4)

• (-15, -4)

• (15, -4)

Convert the equation from vertex form to standard form.

• y = 9x² - 15x + 21

• y = -3x² - 75x - 4

• y = 9x² + 90x + 221

• y = -3x² - 30x - 79

• y = -5x² - 20x - 30

• y = -5x² - 4x - 10

• y = 25x² + 100x + 90

• y = 25x² - 10x - 30

Convert the equation from vertex form to standard form.
