Before the September $11,2001$ attacks, an airline's stock was trading at around $$37$ per share. Immediately after the attacks, the share price dropped by $$16\mathrm{.}40.$ Let U$($t$)$ be this cost at time t$,$ and take t $=11$ to represent September $11,2001.$ What does the given information tell you about

lim$$t$11$U$($t$)?$

lim$$t$11$U$($t$)$

$=$ $$37\mathrm{.}00$

lim$$t$11$U$($t$)$

$=$ $$16\mathrm{.}40$

lim$$t$11$U$($t$)$

$=$ $$26\mathrm{.}70$

lim$$t$11$U$($t$)$
