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
