Suppose that a weight is attached to the end of a swinging pendulum. As the pendulum swings, the distance of the weight from the center of the pendulum's arc varies as shown in the graph.
(GRAPH CAN'T COPY)
Is the relationship between distance and time a function...
a. if time is the input value and distance from the center is the output value?
b. if distance from the center is the input value and time is the output value?
Explain your answers.
