Answer:
the answer would be f: y=-x^3 -4
Elaboration:
You don't show if there's a 4th answer so I'm just assuming you have one, but if there is no option, then I apologize.
Explanation:
y = -x^3 flips the equation, since you are putting the coefficient of x to a negative
y = -x^3 - 4 lowers the equation by 4 on the y axis, setting the equation shown in the graph.
