The video tutorial explains the absolute value function, known as the V graph, and how it can be transformed using the formula X-H+K. The instructor details the roles of parameters A, H, and K in stretching, compressing, and shifting the graph. Examples are provided to illustrate how these transformations affect the graph's appearance, including making it skinnier through vertical stretching.

What shape does the graph of an absolute value function typically form?

• A circle

• A V shape

• A parabola

• A straight line

In the transformation formula X - H + K, what does the parameter 'H' represent?

• Reflection

• Vertical shift

• Horizontal shift

• Vertical stretch

How does the parameter 'A' affect the graph of an absolute value function?

• It stretches or compresses the graph

• It shifts the graph vertically

• It shifts the graph horizontally

• It reflects the graph

If the vertex of the graph is shifted left by 1 unit and down by 4 units, what are the values of H and K?

• H = 1, K = 4

• H = -1, K = -4

• H = 1, K = -4

• H = -1, K = 4

What happens to the graph when it is multiplied by a factor of 2?

• It becomes wider

• It becomes skinnier

• It shifts upwards

• It shifts downwards
