Graphing Quadratic Functions in Vertex Form

This video tutorial introduces quadratics in vertex form, explaining the significance of A, H, and K values in transforming graphs. It provides a step-by-step guide to graphing quadratics using vertex form and demonstrates various examples of graph transformations, including reflections and changes in width.

What form is used to easily understand transformations of quadratic functions?

• Factored form

• Intercept form

• Vertex form

• Standard form

What happens to the parabola when the absolute value of 'a' is greater than 1?

• The parabola shifts vertically.

• The parabola becomes narrower.

• The parabola remains unchanged.

• The parabola becomes wider.

How does a negative 'a' value affect the parabola?

• It shifts the parabola to the right.

• It makes the parabola wider.

• It shifts the parabola upwards.

• It reflects the parabola vertically.

What does the 'h' value in the vertex form represent?

• Direction of the parabola

• Vertical shift

• Width of the parabola

• Horizontal shift

If the equation has 'x - 3', where is the parabola shifted?

• 3 units to the left

• 3 units to the right

• 3 units upwards

• 3 units downwards

What is the vertex of a parabola in vertex form 'f(x) = a(x - h)^2 + k'?

• (a, k)

• (h, a)

• (h, k)

• (k, h)

How does the graph of a quadratic function in vertex form change with an 'a' value of 1/2?

• It reflects vertically.

• It becomes wider.

• It shifts to the right.

• It becomes narrower.

What transformation occurs when the 'k' value is positive?

• Becomes narrower

• Shifts downwards

• Shifts upwards

• Shifts to the left

If a quadratic function in vertex form has a vertex at (2, -4), what are the 'h' and 'k' values?

• h = 2, k = -4

• h = -4, k = 2

• h = -2, k = 4

• h = 4, k = -2

What effect does a negative 'a' value combined with a positive 'k' value have on a parabola?

• Shifts right and becomes wider

• Shifts left and becomes narrower

• Reflects vertically and shifts downwards

• Reflects vertically and shifts upwards
