In this problem, we are going to find the sketch of the graph of y, which is 1 .5, multiplied by e to the negative x.
00:13
So first, we need to find five points on y.
00:17
And for simplicity, we set x equal to negative 2, negative 1, 0, 1, 2, and find the corresponding y values.
00:26
And so we can determine the 5 points.
00:32
So first, when x equal to negative 2, we got this.
00:39
And when x equal to 991 we got this and so on so forth.
00:45
And we know that e is about 2 and 2 .718.
00:53
So the e squared is about 7 .18.
00:56
And so we got the approximate y value so we can determine the five points or some of these points and the last thing is we need to find where these five points on the plot and then connect them so we can get the sketch so let's find where is the first point to the s value is 92, and y value is 92 .695...
