K, so when x=0, then y=-6
so it goes through the y axis (up and down line) at y=-6
now find the x intercepts, or where y=0
factoring we get P(x)=-1(x+2)(x+1)(x-1)(x-3)
so it goes through the y axis at x=-2, x=-1, x=1, and x=3
put those points
now, the function is 4th degree and the leading coefient is negative, so it starts from bottom left and ends at bottom right
so draw a graph starting from bottom left and going through those points and ending at bottom right
since they are all odd multiplicities, the graph goes through the points to the other side of x axis instead of bouncing off

Place Brunhilda at (0,0) which is the location of the intersection of the x and y axis. I'm going to label this point A.
Move 3 units to the right to arrive at point B = (3,0). Then move 2 units up to arrive at point C = (3,2). The next step is to walk 5 units to the left and you get to point D = (-2,2). Finally, we move 2 units south to get to the point E = (-2,0)
When we talk about displacement, we only care about starting and ending points. The stuff in between doesn't matter. We start at (0,0) and end at (-2,0). So the displacement is 2 units to the right or "2 meters west"
Answer: Choice C) 2 m west
Check out the attached image to see a visual of what is going on.
Edit: I mistakenly thought she started at point A. instead she starts at point B. So the answer is actually 5 meters west.
