The position function X(t) of a particle moving along an $X$ axis is $X$ = 4.0 - 6.0$_{t}$ $_{2}$, with $X$ in meters and $t$ in seconds. Graph $X$ versus $t$ for the range -5 s to +5 s. To shift the curve rightward on the graph, should we include the term +20$t$ or the term -20$t$ in $X(t)$?

The position function $X$ $(t)$ of a particle moving along an $X$ axis is $X$ = 4.0 - 6.0$_{t}$ $_{2}$, with $X$ in meters and $t$ in seconds. where does the particle (momentarily) stop?
