Y = 3(x - 1)^2 + 2
y = 3 (x^2 + 1) + 2
y = 3x^2 + 3 + 2
y = 3x^2 + 5
The motion can be modeled as

where
x = the position below the equilibrium position
T = the period of the motion
t = time
The weight returns to its equilibrium position when x = 0.
This occurs when

That is,

Because the weight returns to the equilibrium position when t = 3 s, therefore
T = 12 s
The motion is

When t = 1 s, the position of the weight from equilibrium is

Answer:
The value of X<em> </em>is 6.
Step-by-step explanation:
