The mathematical term for the rate of change of a function is what?

Explanation:
Rate of change is captured by the derivative. The derivative measures how quickly a function’s value changes at a specific point, defined as the limit of the average rate of change as the input change approaches zero: f′(x) = lim h→0 [f(x+h) − f(x)] / h. This gives the instantaneous rate of change and, in geometric terms, the slope of the tangent line to the graph at that point. It’s the best term here because it applies to curves in general, not just straight lines. The slope describes the rate of change for a straight line, which is a constant, while the integral relates to accumulation, and the limit is the procedure used to define the derivative rather than the rate itself.
