In this question, we are required to draw the region bounded by the graphs of the function fx is equal to x cube minus 2x plus 1 and gx is equal to minus 2x and x is equal to 1.
00:23
After that, we are required to find the area of that region and finally we are required to verify the answer with the help of graphing utility.
00:32
So let's see how to solve this question.
00:34
First of all, let's draw the region and the region is shown below.
00:40
So this is the graph for the above functions.
00:43
This line represents x is equal to 1.
00:46
This line represents gx is equal to minus 2x and this curve represents function fx.
00:57
Now let's find the point of intersection and to do so, let's equate function fx and g x so we can write x q minus 2x plus 1 is equal to minus 2x therefore the value of x cube will be equals to minus 1 and hence x will be equals to minus 1 since f x is greater than equals to g x for x which lies between in minus 1 and 1.
01:46
Therefore, the expression to calculate area of the region can be written as a is equal to integration minus 1 to 1, fx minus g x d x.
02:05
Now substitute all the values, so we get area a is equal to integration minus 1 to 1 into x q minus 2x plus 1 plus 2x d x...
