Fill in the Blank

An inventory planner uses the rational function f(x)=8−xx2−7x+12f(x) = \frac{8-x}{x^2-7x+12} to model cost-efficiency. The planner wants to find the specific input values xx that result in an efficiency rating of 3, which requires solving the equation f(x)=3f(x) = 3. Before solving, the planner must identify the domain restrictions to ensure any mathematical solutions are valid in the real world. By setting the denominator x2−7x+12x^2-7x+12 to zero, the planner determines that the restricted values are x=3x = 3 and $x
