Answer:
The graph showing red and blue making a U is the correct choice.
Step-by-step explanation:
The graph P(x) is a square root function. It has a vertex of (0,0) and has the following points:
x f(x)
0 0
1 1
2 2√2
3 2√3
4 4
The image of l(x) = -P(x) changes the points of the function to
x f(x)
0 0
1 - 1
2 - 2√2
3 -2√3
4 -4
This makes the graph reflect across the x-axis. The graph with the U shape made by both functions together is the correct choice.
