$($a$)$ Compute the following. $($If a limit does not exist, enter DNE, and say why.$)$

$$

$$

The limit does not exist because it diverges.

$$ The limit does not exist because the limit from the left does not match the limit from the right.

$\underset{t{14\mathrm{.}75}^{+}}{lim}m(t)=$

$$

The limit does exist.

The limit does not exist because it diverges.

The limit does not exist because the limit from the left does not match the limit from the right,

$\underset{t14\mathrm{.}75}{lim}m(t)=$

$$

The limit does exist.

The limit does not exist because it diverges.

The limit does not exist because the limit from the left does not match the limit from the right.

$m(14\mathrm{.}75)=$

What do the answers to part $($a$)$ tell you about the market depth?

Just prior to $2$:$45pm,$ the S&P market depth was approaching

million shares, but then fell suddenly to

million shares at $2$:$45$ exactly, then immediately following $2$:$45$ it began to recover at values close to

$$ shares.
