Multiple Choice

A technical analyst is using the rational function f(x) = rac{2x-6}{x^2-8x+15} to model the efficiency of a processing node. To find the input xx that results in an efficiency level of exactly 1, the analyst solves the equation f(x)=1f(x) = 1 and obtains the potential values x=7x = 7 and x=3x = 3. Based on the domain of the function, which of these values is an extraneous solution?
