Answer:
Shifting the function y = f(x) to the right by 4 units gives the function y = f(x+4). This shift moves the bounded region 4 units to the left, so we can find the area of the region bounded by y = f(x+4) by subtracting the area of the unbounded region to the left.
Since the area of the original bounded region is 8 units², the unbounded region to the left has area 4 units². Therefore, the area of the region bounded by y = f(x+4) is the area of the original bounded region (8 units²) minus the area of the unbounded region to the left (4 units²), which is:
8 - 4 = 4 units²
So, the area of the region bounded by the x-axis and the function y = f(x+4) is 4 units².
