Which is the variable in the polynomial \(p(u)=13u^3-2u+9\)?
Answer and explanation
Correct answer: u
A variable is a letter whose value can change. In this polynomial, changing u changes the value of the polynomial, so u is the variable. Here, p is the name of the polynomial, while 13 and 9 are constants. Exam tip: The letter appearing with powers in a polynomial is usually the variable.
