Rearrange Quadratic Functions to Standard Form

What is the name of this form of a quadratic equation:

• vertex form

• standard form

• factored form

• zero form

• x²+9

• x²-10x+9

• x²-10x-9

• x²+10x+9

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

Convert the equation from vertex form to standard form

What is the name of this form:
y = ax² + bx + c

• vertex form

• standard form

• factored form

• zero form

The standard form of a quadratic function is

• ax² + bx + c

• a(x - h)² + k

• y - y₁ = m(x - x₁)

• Ax + By = C
