If \(p(x)=\frac{5}{6}x-10\), what is (p(12))?
Answer and explanation
Correct answer: 0
Substituting \(x=12\), \(p(12)=\frac{5}{6}\times 12-10=10-10=0\). Hence, the correct answer is \(0\). The value \(-10\) is only the constant term, not the value of the polynomial at \(x=12\). Exam tip: For a polynomial with a fractional coefficient, multiply first and then add or subtract.
