For each equation a. solve for the domain = {-4,0,1}, and b. determine if it is a function x+y=12, x=3-y, y=8+x^2

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.
