If (p(x)=8x-13), what is (p(0))?
Answer and explanation
Correct answer: \(-13\)
Given \(p(x)=8x-13\), substitute \(x=0\): \(p(0)=8\times0-13=-13\). Hence, option C is correct. Choosing \(13\) is a common sign error because the constant term is \(-13\), not \(+13\). Exam tip: at \(x=0\), only the constant term of a polynomial remains.
