Answer:
C. f'(x) = lim(h→0) [(f(x+h) − f(x)) / h]
Step-by-step explanation:
The first derivative is the slope between two points as the distance between those points approaches 0. Slope is Δy/Δx. Choice D is a valid way to write the first derivative. It is the slope between the points (x, f(x)) and (x+h, f(x+h)). Choice C is not a valid definition.
Answer:
C
Step-by-step explanation:
The same x value cannot be used more than once or it isn't a function.
