What is the maximum value of the function \(f(x)=\frac{1}{x^2-6x+10}\), where \(x\in\mathbb{R}\)?

Answer and explanation

Correct answer: \(1\)

Complete the square in the denominator: \(x^2-6x+10=(x-3)^2+1\). Since \((x-3)^2\ge 0\), the denominator has minimum value \(1\), attained at \(x=3\). Therefore, the maximum value of \(f(x)\) is \(\frac{1}{1}=1\). For instance, \(\frac{1}{10}\) is not the maximum; it occurs only for particular values of \(x\). Exam tip: when the denominator is positive, the reciprocal is maximized when the denominator is minimized.
