-
c (0, 7) —> c’
-
d (4, 5 —> d’
-
e (4, 0) —> e’

fill all of there out : ) will give brainiest!

The graph shows the distance y, in inches, a pendulum moves to the right (positive displacement) and to the left (negative displacement), for a given number of seconds x. how many seconds are required for the pendulum to move from its resting position and return? enter your answer in the box.

How do i do this? i don’t understand
