$\"\"$

The displacement of a spring is $\"\"$ , where $\"\"$ is the displacement in feet and $\"\"$ is the time in seconds.

Graph the function $\"\"$ on interval $\"\"$ .

$\"\"$

Find a value of $\"\"$ past which the displacement is less than $\"\"$ from equilibrium.

$\"\"$

The displacement is less than $\"\"$ is $\"\"$ .
