What are the differences between vertical and horizontal translations?

Vertical: Shifts up/down, affects y-values. Horizontal: Shifts left/right, affects x-values.

What are the differences between vertical and horizontal dilations?

Vertical: Stretches/shrinks vertically, affects y-values. Horizontal: Stretches/shrinks horizontally, affects x-values.

What is the difference between a vertical stretch and a vertical shift?

Vertical stretch: Changes the shape of the graph by multiplying y-values. Vertical shift: Moves the graph up or down without changing its shape.

How do horizontal stretches and compressions differ?

Horizontal stretch: Expands the graph horizontally. Horizontal compression: Shrinks the graph horizontally.
