Answer:
3rd
Explanation:
Negative suggests that whatver the graph is, it's the opposite of the original function. That leaves us with 2 and 3 (since 1st one is positive x^3 )
Now, the degree 3 tells you that it has to be number3 because that's the 3rd degree graph, Since second one is a upside down parabola which means -x^2
Hope this cleared things up for you!
