Evaluating a Combined Logistics Cost Index

An inventory control coordinator at a regional distribution center uses a combined efficiency model to predict operating costs. The model is represented by the product function (f⋅g)(x)=x3+x2−52x−28(f \cdot g)(x) = x^3 + x^2 - 52x - 28, which is derived from the base functions f(x)=x−7f(x) = x - 7 and g(x)=x2+8x+4g(x) = x^2 + 8x + 4. To find the net efficiency index when the shipment volume index xx is 2, the coordinator must evaluate (f⋅g)(2)(f \cdot g)(2).

Recall the standard algebraic procedure for evaluating a product function. Write the mathematical expression showing the direct substitution of 2 into the expanded product function (f⋅g)(x)(f \cdot g)(x), and provide the final simplified integer value of (f⋅g)(2)(f \cdot g)(2).
