Which of the following strategies does NOT help establish an intellectual need for deductive proof?
a. Have students produce several examples, observe what happens to measurements when dragging, make a conjecture, and then try to explain why the conjecture is true.
b. Have students produce several examples, observe what happens to measurements when dragging, make a conjecture, and record the conjecture in their notebooks as an established result.
c. Present students with a situation leading them to make geometric conjectures that do not hold up when they examine examples in a DGE.
d. Provide open-ended tasks that prompt students to make conjectures, provide justifications, and build chains of reasoning.

Solve the problem.An object of mass m attached to a coiled spring with damping factor b is pulled down a distance a from its rest position and then released. Assume the positive direction of the motion is up and the period of the first oscillation is T. Write an equation that relates the distance d of the object from its rest position after t seconds. m = 15 g; a = 11 cm; b = 0.7 g/sec; T = 3 sec
