1. To determine if a transformation is vertical or horizontal, we need to know the context or the function involved. 2. Vertical transformations affect the output values (y-values) of a function, such as vertical shifts or stretches/compressions. 3. Horizontal transformations affect the input values (x-values), such as horizontal shifts or stretches/compressions. 4. Without a specific function or transformation given, we cannot definitively say if it is vertical or horizontal. 5. Please provide the function or transformation details for a precise answer.
