If (p(x)=x-20), in which form can (p(x)) be written?
Answer and explanation
Correct answer: \(ax+b\)
The given polynomial is \(p(x)=x-20\). It can be written as \(1x+(-20)\), so it is a linear polynomial of the form \(ax+b\), where \(a=1\) and \(b=-20\). The form \(ax^2+b\) is quadratic and must contain an \(x^2\) term. Exam tip: identify the type of a polynomial from its highest power; here, the highest power of \(x\) is 1.
