Math Calculator

You do not always need a calculator to do math nor do you need a graph. Sometimes you can just look at an equation and do math. That is why I always say, work smarter not harder. The objective of this project is to study polynomial of degree equations by using Microsoft word and excel. Also identify ways to come up with the answer different ways without a calculator or graph. Polynomials include end behavior, zeros, local extreme, rules of signs, intermediate value theorem, rational zero theorem, remainder theorem, remaining zeros, and intercepts. An end behavior is the appearance of the graph when the graph goes the opposite direction. The end behavior is based off the x-axis. If the graph starts in the negative and proceeds to the positive,

It can also have more than once bend. In local extrema you can either have a maximum or minimum. To find the exact numbers of the local extrema you have to use the calculator. First you go to Y= and type in the equation , then go to zoom and click on zoom fit and press enter, after you press enter the graph should pop up. Finally go to Y= and press 2nd graph and it should be able to give you the points of the local extrema. To find the local extrema while looking at your polynomial you would look at D. If F of X is greater than or equal too D you have a local minimum. However, if F of X is less than or equal to you have a local maximum. My polynomial does not have any local extrema. Zeros in polynomial are the same as x-intercepts and roots. To Find the roots in an equation you have to get x by itself. For instance, Y= 2x+10, you can use the calculator and press second graph to find the exact points. There are two types of zeros, complex and real. Finding the exact number of zeros make take some time. It mostly consist of algebra with adding, subtracting, multiplying, and dividing. When finding the zeros the best way to do it is use the graphing calculator. First you see where the graph crosses the x- axis and that can quickly narrow down your list of possible
