A taxi charges a fixed fee of ₹50 and ₹12 per kilometre. If the distance travelled is represented by \(x\), which statement about \(C(x)=12x+50\) is correct?

Answer and explanation

Correct answer: It is a linear polynomial of degree 1.

In \(C(x)=12x+50\), the highest exponent of the variable \(x\) is 1, and the coefficient of \(x\), 12, is non-zero. Therefore, it is a linear polynomial of degree 1. The number 50 is only the constant term; it does not make the entire expression constant. Exam tip: find a polynomial’s degree by identifying the highest exponent of its variable.
