Graphing Quadratics and Factoring Techniques

What is the vertex form of a quadratic equation?

• y = ax^2 + bx + c

• y = mx + b

• y = a(x - m)(x - n)

• y = a(x - h)^2 + k

In the vertex form y = a(x - h)^2 + k, what does the 'h' represent?

• The y-intercept

• The slope of the parabola

• The x-coordinate of the vertex

• The y-coordinate of the vertex

How do you determine the direction in which a parabola opens in vertex form?

• By the sign of 'a'

• By the y-intercept

• By the value of 'h'

• By the value of 'k'
