Hello, everybody.
00:02
In this video, i'm going to be showing you how to solve exercise 15 from chapter 1, section 1 of calculus early transcendentals.
00:11
Now, i would like to heavily advise that you have the textbook in front of you while you watch this video, as i have not included the given graph into this video.
00:21
However, i have included a table here, just on the upper right, of values of the functions, f and g, produced as for certain values of x.
00:31
And these are taken directly from the graph.
00:36
Now, the question, given these values that you can obtain from this graph, asks us to evaluate certain composite expressions involving these functions, which are the ones given below here? let's start with the first.
00:53
F -o -g -2 is the same thing, excuse me here, is the same thing as f of g of 2.
01:07
Now notice that g of 2, we can find directly from the table, g of 2 is just 2.
01:15
So this is just equal to f of 2.
01:21
And now f of 2, f of 2, f of 2, is 4.
01:27
So the answer here is 4.
01:32
Now for the second one, we can use a table to see that f of 2, f of 2 is 4.
01:40
So this expression is equal to g of 4, which is just 1...
