If (q(x)=0x^7+0x^4+15x-6), what is the degree of (q(x))?
Answer and explanation
Correct answer: 1
Terms with coefficient 0 do not contribute to a polynomial. Thus the expression reduces to \(15x-6\). The highest power of \(x\) in this polynomial is \(1\), so its degree is \(1\). Degree \(0\) applies to a non-zero constant polynomial, not to this linear polynomial. Exam tip: first remove zero-coefficient terms, then identify the highest exponent of the variable left.
