What is the vertex form of a quadratic function?

• f(x) = a(x - h)^2 + k

• f(x) = ax^2 + bx + c

• f(x) = ax^2 + bx

• f(x) = a(x - p)(x - q)

What does the vertex form primarily help to identify in a quadratic function?

• X-intercepts

• Y-intercept

• Maximum or minimum values

• Coefficient of x

What is the significance of the coefficient 'a' in the vertex form of a quadratic function?

• Determines the width of the parabola

• Indicates the direction of the parabola

• Both A and B

• Neither A nor B
