In the vertex form of a quadratic equation, what does 'H' represent?

• The coefficient of the squared term

• The maximum value of the quadratic

• The x-coordinate of the vertex

• The y-intercept

How do you determine the axis of symmetry in vertex form?

• y = a(x - k)^2 + h

• y = a(x + k)^2 + h

In intercept form, what do the values inside the parentheses represent?

• The coefficients of x

• The x-intercepts of the parabola
