Exploring Absolute Value Transformations and Reflections

The video tutorial explains transformations of functions, focusing on compression, stretch, and reflection. It describes how multiplying a value in front of an absolute value function affects its graph, leading to either a stretch or compression. The tutorial then introduces reflection, showing how a negative sign in front of the absolute value function reflects the graph over the x-axis. The video also covers graphing these transformations and discusses the concept of the axis of symmetry, emphasizing its dependence on the vertex position.

What happens to a function when it undergoes a stretch transformation?

• It shifts downwards.

• It shifts upwards.

• It becomes narrower.

• It becomes wider.

What is the effect of multiplying an absolute value function by a value greater than 1?

• It shifts the function left.

• It causes a compression.

• It reflects the function.

• It causes a stretch.

If a value between 0 and 1 is multiplied to an absolute value function, what transformation occurs?

• Translation

• Compression

• Reflection

• Stretch

What transformation is introduced when a negative sign is multiplied in front of the absolute value function?

• Stretch

• Translation

• Compression

• Reflection

What is the vertex of the function f(x) = -|x|?

• (0, 0)

• (1, 1)

• (1, 0)

• (0, 1)

What is the axis of symmetry for the function f(x) = -|x|?

• x = 1

• x = 0

• y = 0

• y = 1

What happens to the graph of the function f(x) = |x| when it is reflected?

• It flips over the x-axis.

• It flips over the y-axis.

• It shifts to the left.

• It shifts to the right.

What should you ensure when entering a negative sign in the calculator for the function f(x) = -|x|?

• Use the division button.

• Use the negative button.

• Use the subtraction button.

• Use the multiplication button.

What is the parent function of the absolute value transformations discussed?

• f(x) = 1/x

• f(x) = x

• f(x) = |x|

• f(x) = x^2
