Which polynomial is linear in (x)?
Answer and explanation
Correct answer: \(4x+2\)
A linear polynomial has highest power 1 of the variable. In \(4x+2\), the highest power of \(x\) is 1, so it is linear. \(4x^2+2\) is quadratic and \(4x^3+2\) is cubic, while \(4\) is a constant polynomial. Exam tip: identify the degree by looking for the highest exponent of the variable.
