If \(p(x)=\frac{3}{4}x-6\), what is (p(8))?
Answer and explanation
Correct answer: 0
Substituting \(x=8\), \(p(8)=\frac{3}{4}\times 8-6=6-6=0\). Hence, the correct answer is 0. Option 6 is only the value of \(\frac{3}{4}\times8\); subtracting 6 is also necessary. Exam tip: While evaluating a polynomial, substitute the given value of \(x\) carefully in every term.
