PLEASE HELP ME?? 10 POINTS?! HELP ASAP.

Answer 1

Last graph (D)

Explanation:

`f(x)=x(x-2)(x+4)`

Find the zeros:

`f(x)=0\iff x(x-2)(x+4)=0\iff x=0\ \vee\ x-2=0\ \vee\ x+4=0\\\\\boxed{x=0}\ \vee\ \boxed{x=-2}\ \vee\ \boxed{x=-4}`

A graph with that x-intercepts is the last graph.

The second and third graphs are graphs of the quadratic function.

We have the function third degree (graph A and D).
