Algebra 2 Review (Unit 1 - 2)

A parabola is the set of all points equidistant from the focus and the directrix.

• true
• false

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)

The focus is always inside the parabola.

• true
• false

The 'p' value represents the distance between the vertex and the focus AND the vertex and the directrix.

• True
• False

The sign of the 'p' value determines if the graph opens upward or downward.

• True
• False
