Quadratic Different Forms

• y = x(x + 7)

• y = x(x - 7)

• y = x( 7x )

• y = x( -7x )

Write the equation of the quadratic function that has a x-intercepts at 2 and 4 and passes through the point (3, 4).

• y = -4(x - 2)(x - 4)

• y = -4(x + 2)(x + 4)

• y = 4(x - 2)(x - 4)

• y = -0.25(x - 2)(x - 4)

Write an equation in standard form for a quadratic with zeros (0, 0) and (7, 0).

Use the vertex form to write the equation of the parabola.

• y = 3(x - 2)² + 2

• y = 3(x - 2)² - 2

• y = 3(x + 2)² + 2

• y = (x + 2)² + 2

Suppose a parabola has vertex (-8, -7) and also passes through the point (-7,-4). Write the equation of the parabola in vertex form.

• y = (x + 8)² - 7

• y = 3(x - 8)² - 7

• y = 3(x + 8)² - 7

• y = 3(x + 8)² + 7

• f(x) = (x - 4)² + 17
• f(x) = (x - 4)² - 17
• f(x) = (x - 4)² + 65

Convert to Intercept/Factored Form (Try a GCF First!) 2x² + 2x - 84

• (x-6)(2x+14)

• (x+7)(2x-12)

• (x-4)(2x+21)

• 2(x+7)(x-6)

Convert to Intercept Form.   y=x^2+14x+48

• y = (x+8)(x+6)

• y = (x+8)(x-6)

• y = (x-6)(x-8)

• y = (x-8)(x+6)
