What is the graph of the zero polynomial \(p(x)=0\)?
Answer and explanation
Correct answer: The whole x-axis (i.e. the line \(y=0\))
The zero polynomial \(p(x)=0\) yields \(y=p(x)=0\) for every real x. Thus the graph consists of all points whose y-coordinate is zero — the entire line \(y=0\), i.e. the x-axis. Option D is incorrect because the graph is not just the origin; it contains infinitely many points (every (x,0)). Option B is wrong since the y-axis is the vertical line \(x=0\), not \(y=0\). Option C is false because a value exists for every x. Exam tip: Remember the graph of a polynomial is the set of points \((x,p(x))\); plug in the definition to see the shape quickly.
