If (p(x)=3x+2), what is (p(2))?
Answer and explanation
Correct answer: 8
Substitute 2 for x in the polynomial: \(p(2)=3\times2+2=6+2=8\). Therefore, the correct answer is 8. The value 6 represents only \(3\times2\); the constant term 2 must also be added. Exam tip: To find the value of a polynomial, replace every x with the given number and then simplify carefully.
