If \(p(x)=\frac{2}{3}x+5\), what is (p(6))?
Answer and explanation
Correct answer: 9
Substituting \(x=6\), we get \(p(6)=\frac{2}{3}\times 6+5=4+5=9\). Hence, 9 is the correct option. Option 8 may result from incorrectly evaluating \(\frac{2}{3}\times6\) as 3; its value is 4. Exam tip: while evaluating a polynomial, substitute the given value for every \(x\), then perform multiplication before addition or subtraction.
