If (p(x)=5x+6), what is (p(4))?
Answer and explanation
Correct answer: 26
To find the value of the function, substitute 4 for x: \(p(4)=5\times4+6=20+6=26\). Therefore, the correct answer is 26. The value 20 is only \(5\times4\); the constant term 6 must also be added. Exam tip: While evaluating a polynomial, substitute the given value carefully in every term.
