To determine which absolute value equation corresponds to the lower function in the graph, we need to analyze each option in terms of its vertical position (y-value) and the transformations involved:
- y = 2|x| - 2: This function has a vertical stretch of 2 and shifted down by 2.
- y = |x| - 4: This function is vertically shifted down by 4.
- y = |x - 4| - 1: This function is shifted to the right by 4 and down by 1.
- y = 12|x| - 4: This function has a vertical stretch of 12 and is shifted down by 4.
Assessing these equations:
- The first option would be more positive than the others due to the vertical stretch of 2 and starting at (0, -2).
- The second option starts at y = -4, which is lower than the first.
- The third option, y = |x - 4| - 1, starts from (4, -1), which is not lower than any of the previous functions.
- The fourth option starts at (0, -4), making it similar to the second option due to the vertical stretch.
From this analysis, the equation y = |x| - 4 creates the lower function because it has the intercept at the lowest y-value of -4 for a wider span than the others, indicating it has the greatest downward shift without additional vertical stretch.
So the answer is: y = |x| - 4.
