What are the degree and type of (p(x)=7x-4)?

Answer and explanation

Correct answer: Degree 1, linear polynomial

The degree of a polynomial is the highest power of its variable with a non-zero coefficient. Here, x has power 1 in 7x, while -4 is a constant term. Therefore, p(x)=7x-4 has degree 1 and is a linear polynomial. Degree 0 applies only to non-zero constant polynomials. Exam tip: identify the type of a polynomial by finding the highest exponent of the variable.
