These 14 task cards focus on the relationship between a function and its derivative in all representations (graph, table, word problem, and function rule). The meaning of the function vs the meaning of the derivative...what we learn from f(x) vs what we learn from f'(x). Students must know that the derivative function gives the slope of the tangent line (or the slope of the curve), but do not need to be able to compute derivatives. Answers are provided.
