Which of the following is the Factored Form of a quadratic function?

• f(x) = mx + b

• f(x) = ax² + bx + c

• f(x) = a(x - m)(x - n)

• f(x) = a(x - h)² + k

What are the x-intercepts of the parabola?

y = -3(x + 5)(x - 9)

• (-5, 0) and (9, 0)

• (5,0) and (-9, 0)

• (5, 0) and (9, 0)

• (-3, 0) and (5, 0)and (-9, 0)

Which equation is the standard form of a quadratic function?

• f(x) = mx + b

• f(x) = a(x - m)(x - n)

• f(x) = ax² + bx + c

• f(x) = a(x - h)² + k

In factored form you can see the ______ of the graph easily.

• y-intercept

• vertex

Which polynomial is in standard form?

• x²-2x³+4x-1

• 8x-3+5x⁴

• -x⁵+x³-2+3x

• 9x⁵+7x-14

Put in Standard Form.
12 - 3x³ - 10x - x²

•  - 3x³ - x² - 10x + 12

•  3x³ - x² + 10x + 12

• 12 - 3x³ - 10x - x²
  It is in Standard Form.

• 12 - 10x - 3x³ - x²
