Quadratic Functions Quiz

What is the general form of a quadratic function?

• y = ax^3 + bx^2 + cx + d

• y = ax^2 + bx + c

• y = ax^2 + bx

• y = ax^2 + bx + c + d

Write the vertex form of a quadratic function.

• y = a(x+h)^2 + k

• y = a(x-h)^2 - k

• y = a(x+h)^2 - k

• y = a(x-h)^2 + k

How do you find the x-coordinate of the vertex of a quadratic function?

• x = b / (2a)

• x = -b / (2a)

• x = -b / a

• x = -2b / a
