If (p(x)=2x+3), what is the value of (p(1))?
Answer and explanation
Correct answer: 5
Given \(p(x)=2x+3\), substitute 1 for \(x\): \(p(1)=2\times1+3=5\). Therefore, the correct answer is 5. The value 4 would result from incorrectly forgetting to add the constant term 3. Exam tip: To evaluate a polynomial, replace the variable with the given number and perform each operation carefully.
