If (p(x)=5x-4), what is (p(0))?
Answer and explanation
Correct answer: -4
Given \(p(x)=5x-4\), substitute \(x=0\): \(p(0)=5\times 0-4=-4\). Therefore, \(-4\) is correct. Option 0 is incorrect because only the term \(5x\) becomes zero; the constant term \(-4\) remains. Exam tip: when finding \(p(0)\), the constant term of a polynomial is left.
