For the function \(f(x)=x^3\), what is the relation between \(f(2)\) and \(f(-2)\)?

Answer and explanation

Correct answer: \(f(-2)=-f(2)\)

\(f(2)=2^3=8\) and \(f(-2)=(-2)^3=-8\), so \(f(-2)=-f(2)\). This shows that \(f(x)=x^3\) is an odd function, whose graph is symmetric about the origin. Exam tip: If \(f(-x)=-f(x)\), the function is odd.
