00:24
In part a, we say, what is the domain of the function y? well, we need to think about the reasonable domain of the function y.
00:38
So in this case, i know that d, the dividend, can't be negative.
00:46
So we need d to be greater than or equal to zero.
00:54
While the price per share, that has to be positive.
00:59
You can't have a price per share of zero because dividing by zero doesn't make sense.
01:06
And besides, if the price per share were zero, the company would be bankrupt.
01:11
So p has to be greater than zero.
01:15
Those are the two constraints on the domain of the function in part b.
01:23
They say the annualized dividend of ibm corporation for the year 2011 was $3.
