If \(q(x)=x^3-x\), what is the value of \(q(0)\)?

Answer and explanation

Correct answer: 0

Substituting \(x=0\) in the polynomial gives \(q(0)=0^3-0=0-0=0\). Therefore, the correct answer is B, 0. Do not confuse \(0^3\) with 1; every positive power of zero is 0. Exam tip: To evaluate a polynomial, substitute the given value at every occurrence of \(x\).
