In mathematics, the volume of a solid object is the amount of three-dimensional space enclosed by the boundaries of the object. The volume of a solid of revolution (such as a sphere or cylinder) is calculated by multiplying the area of the base by the height of the solid.

A review is a form of evaluation, analysis, and judgment of a body of work, such as a book, movie, album, play, software application, video game, or scientific research. Reviews may be used to assess the value of a resource, or to provide a summary of the content of the resource, or to judge the importance of the resource.

he is clear. So when you raid here, So for part A, we're gonna find the derivative of C of X, and we get for X plus four over three X to the 2/3 so we're gonna find when it's increasing and decreasing. It's increasing when the derivative is bigger than zero and decreasing when a smaller than zero. So we see that it is increasing when exes between one negative one and infinity and increasing when it's between decreasing. When it's between negative infinity and negative one For part B, we see a local minimum at sea of negative one, which is equal to negative three. Since that changes from decreasing to increasing report. See, we're finding the second derivative. Let me get for X minus two over nine x to the 5/3 and this is where the second derivative equal to thorough. So we get X is equal to two, and when X is equal to zero, it's undefined. So we take the intervals Negative infinity comma zero. We choose C double derivative of negative one and this is bigger than zero, which means it's calm. Keep up between the interval zero and two. We choose one just less than zero in between two and infinity, you choose three, which is bigger than zero. So the changes con cavity at zero and two. So there are inflection points zero comma zero into comma 7.56 When we plug it into the orginal equation Part D we just draw a graph and I love something like this
