We’re not going to be doing much with asymptotes here, but it’s an easy fact to give and we can use the previous example to illustrate all the asymptote ideas we’ve seen in the both this section and the previous section. Let’s start with the first limit. 3.7 - Maximum Volume A rectangular package to be sent by... Ch.

Square roots are ALWAYS positive and so we need the absolute value bars on the \(x\) to make sure that it will give a positive answer. Find the vertical asymptote (s) (if any) of the graph of the function.

Infinite limits at infinity tell us about the behavior of polynomials for large-magnitude values of x. 3 - Finding Numbers Find two positive numbers such... Ch. In this case the indeterminate form was neither of the “obvious” choices of infinity, zero, or -1 so be careful with make these kinds of assumptions with this kind of indeterminate forms. This condition is here to avoid cases such as \(r = \frac{1}{2}\). Let’s start with the first limit and as with our first set of examples it might be tempting to just “plug” in the infinity.

However, at this point it becomes absolutely vital that we know and use this fact. The graph shows the profit P... Ch. In other words, we are going to be looking at what happens to a function if we let \(x\) get very large in either the positive or negative sense. Using this fact the limit becomes. It will also have a vertical asymptote. 3.6 - EXPLORING CONCEPTS Sketching a Graph Sketch a... Ch. 3.8 - True or False?

Or, in the limit we will get zero. 3.6 - EXPLORING CONCEPTS Points of Inflection Is it... Ch. This is not something that most people ever remember seeing in an Algebra class and in fact it’s not always given in an Algebra class. Remember that all you need to do to get the factoring correct is divide the original polynomial by the power of \(t\) we’re factoring out, \({t^5}\) in this case. 3.3 - EXPLORING CONCEPTS Transformations of Functions In...
