Three Forms Quadratic

What information can I find from this form of the equation?

• x-intercepts: x = 9 and x = 10

• y-intercept: y = 19

• vertex: (9, 10)

What information can I find from this form of the equation? f(x ) = (x - 5)2 + 8

• x-intercepts: x = 5 and x = 8

• y-intercept: y = 5

• vertex: (5, 8)

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

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)

Identify the vertex.

• (5, 2)

• (5, -2)

• (-5, 2)

• (-5, -2)

Given the quadratic:
y=(x+3)(x-3)

Find the x-intercepts.

• (0,0) and (3,0)

• (-3,0) and (3,0)

• (0,0) and (0,-9)

• only (3,0)
