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.

Polynomial that can be factored as (3x-4)(3x+4)

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2
