Quadratic in Vertex Form

What is the vertex form of a quadratic equation?

• 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 vertex of a quadratic equation in vertex form?

• x = b/2a

• x = -b/2a

• x = -a/2b

• x = a/2b

What is the axis of symmetry of a quadratic function in vertex form?

• Horizontal line passing through the vertex.

• Diagonal line passing through the vertex.

• Curved line passing through the vertex.

• Vertical line passing through the vertex

How do you graph a quadratic function in vertex form?

• Identify the vertex coordinates and the direction of the parabola, plot the vertex, determine the shape of the graph based on 'a', plot additional points, and connect them to create a smooth curve.

• Plot the y-intercept and draw a straight line through it.

• Identify the x-intercepts and plot them, then draw a straight line connecting them.

• Determine the axis of symmetry and plot points on either side of it, then connect the points to form a curve.
