Higher-order derivatives are useful because they serve as coefficients in polynomial approximations of functions, specifically in Taylor series. The values of the function and its successive derivatives at a point allow for constructing increasingly accurate local approximations.

Conditions: The function is sufficiently smooth near the expansion point for finite-order approximation.; The context is local polynomial approximation (Taylor series).

To evaluate the right-hand limit ($\lim_{x \to c^+} f(x)$), trace the graph starting from x-values greater than c and moving leftward toward c. Observe the height (y-value) that the curve approaches.

Conditions: Evaluating the limit from the right side (inputs strictly greater than c).; The graph shows a clear trend toward a finite y-level.
