If (Q(x)=6+2x), what is (Q(1))?
Answer and explanation
Correct answer: 8
Given (Q(x)=6+2x), substitute (x=1): \(Q(1)=6+2(1)=6+2=8\). Therefore, the correct answer is 8. The value 10 would result if the term were 4x instead of 2x. Exam tip: To evaluate a polynomial, replace the variable with the given number throughout the expression.
