^{3 }Now you have f(2)=0, which means that f(x) has zero at point x=2 and its graph crosses x-axis at x=2. To get an idea how the graph should look like, first you can draw graph of the function, for instance, f(x)=x

^{3}-4x or f(x)=-x

^{3}+4x (or any other

^{ }function which satisfies both conditions).
