Step-by-step explanation:
The mathematical concept that involves finding the linear approximation of a multivariable function at a specific point is Tangent Plane Calculation (option A).
In calculus, the tangent plane calculation is used to find the linear approximation of a multivariable function at a given point. This involves finding the equation of the tangent plane to the surface represented by the function at that point. The tangent plane serves as a linear approximation to the function near the point of interest.
For example, if you have a function f(x, y), the linearization at a specific point (a, b) is given by:
f(x, y) ≈ f(a, b) + fx(a, b)(x - a) + fy(a, b)(y - b)
