To determine which equation creates the upper function in the graph, we need to understand how the absolute value function affects the position of the graph vertically.
- y = |x| - 3: This graph is shifted down 3 units.
- y = |x - 3|: This graph is shifted to the right by 3 units, remaining at the same vertical level as the basic |x| function.
- y = |x| + 3: This graph is shifted up 3 units, moving further away from the x-axis.
- y = |x + 3|: This graph is shifted to the left by 3 units, but keeps the same vertical position as the basic |x| function.
Since you are looking for the equation that creates the upper function in the graph, the correct response would be:
y = |x| + 3.
This function shifts the absolute value graph upwards, making it the upper function compared to the others listed.
