If \(p(x)=2x^2-7x+3\), what is the value of \(p(3)\)?
Advertisement
Answer and explanation
Correct answer: 0
To find \(p(3)\), substitute 3 for \(x\): \(p(3)=2(3)^2-7(3)+3=18-21+3=0\). Therefore, the correct answer is 0. Exam tip: replace \(x\) with the given value in every term; the value 18 from considering only \(2(3)^2\) is not the value of the complete polynomial.
