The analysis of a function's slope or rate of change is a primary focus of numerical differentiation. Numerical differentiation is a method used to approximate the derivative of a function at given points. The derivative provides a measure of how a function changes as its input changes, which is essentially the definition of slope.

When you compute the derivative numerically, you estimate how the function's value changes in response to small changes in the input, thereby revealing the function's instantaneous rate of change at specific points. This is particularly useful in scenarios where analytic differentiation is complex or where data is gathered experimentally, making it impractical to derive an explicit formula for the derivative.

In contrast, continuity involves understanding whether a function is smooth without breaks or jumps, while maximum and minimum points relate to optimization and require techniques beyond simple differentiation. The overall shape of a function is more of a graphical or visual assessment, which may consider the first and second derivatives but doesn’t specifically center on rate of change itself. Thus, focusing on the slope or rate of change encapsulates the essence of what numerical differentiation is all about.
