For the polynomial \(p(x)=x^2+3x+2\), what is the value of \(p(1)\)?
Answer and explanation
Correct answer: 6
To find \(p(1)\), substitute 1 for every \(x\) in the polynomial: \(p(1)=1^2+3\times1+2=1+3+2=6\). Therefore, the correct answer is 6. The nearby option 5 may result from adding the terms incorrectly or omitting a term. Exam tip: substitute the given value for each occurrence of the variable before simplifying.
