In this problem, we are given a table of data points describing the bird count as a function of time.
00:08
We want to sketch a rough graph of our bird count.
00:14
Let's start by drawing an x -axis for the year and a y -axis for the count.
00:34
So in 1990, there were 74 bird counts.
00:53
So let's put the origin as 1980.
00:56
Oh, excuse me, let's just cut the graph.
01:08
We'll start in here at 1980.
01:14
74 birds were observed.
01:27
In 1995, there were 82.
01:29
So let's draw 1985, 1990, 1995, 2000, 2005, and lastly 2010.
01:56
And now i'm just filling in our y -axis.
02:41
So our bird count on the y -axis goes from 74 to 107.
02:48
So starting at 70 and increasing to 110.
03:09
So 1980, there were 74 bird counts.
03:14
In 1985, there were 92.
03:19
In 1990, 88.
03:32
In 1995, 107.
03:39
In 2000, there were 70...
