Which linear polynomial gives (9) at (x=0)?
Advertisement
Answer and explanation
Correct answer: \(x+9\)
For a linear polynomial \(ax+b\), substituting \(x=0\) gives \(b\), the constant term. For \(x+9\), we get \(0+9=9\), so it is correct. In contrast, \(x-9\) gives \(-9\), while \(9x\) gives \(0\). Exam tip: At \(x=0\), the value of a polynomial is its constant term.
