Which polynomial is linear and has a negative leading coefficient?
Answer and explanation
Correct answer: -3x+4
A linear polynomial has degree 1 and is of the form ax+b, where a ≠ 0. In -3x+4, the highest power of x is 1 and its leading coefficient is -3, which is negative. x^2-3 is quadratic, while 7 is a constant polynomial. Exam tip: To find the leading coefficient, look at the coefficient of the term with the highest power.
