If \(f(x)=3x^2-2x+5\), which of the following functions is the additive inverse of \(f\), that is, satisfies \((f+g)(x)=0\) for every real \(x\)?

Answer and explanation

Correct answer: \(g(x)=-3x^2+2x-5\)

For an additive inverse, the sign of every corresponding term changes. Thus \(g(x)=-(3x^2-2x+5)=-3x^2+2x-5\). In option B, the sign of \(3x^2\) is unchanged. Exam tip: place a minus sign outside the complete function first.
