You could use many different types of graphs, depending on what kind of data you're trying to share.]]> 2018-08-29 14:06:22 UTC https://padlet.com/9956845/2tov7w6loflu/wish/276225967 Why do we bother using/making graphs? 9956845 https://padlet.com/9956845/2tov7w6loflu/wish/276227066 Making & using graphs can be helpful when trying to show a visual aspect of things. ]]> 2018-08-29 14:08:45 UTC https://padlet.com/9956845/2tov7w6loflu/wish/276227066 How do you graph y=x^2? 9956845 https://padlet.com/9956845/2tov7w6loflu/wish/276889003
-you would plug in a number for x, so lets just use 4.
then you would solve the equation. if y=4^2, then y would have to equal 16.
- so your graph would turn out like an upward facing parabola. it would only go out to 4, because that's the "x", and now it would only go up to 16, because that's the "y."
-the coordinates would be (2,4), and (-2,4)]]> 2018-08-31 13:47:54 UTC https://padlet.com/9956845/2tov7w6loflu/wish/276889003 Here's a list of what I know about power functions and exponents: 9956845 https://padlet.com/9956845/2tov7w6loflu/wish/281308710 -how to change  a negative exponent to a positive by using a fraction.
-what different types of power functions there are and how they're different and how they're the same.]]> 2018-09-14 13:53:57 UTC https://padlet.com/9956845/2tov7w6loflu/wish/281308710 What I learned from today's work 9/28/2018 9956845 https://padlet.com/9956845/2tov7w6loflu/wish/286967067 Today in math class I learned about  the inverse of numbers and power functions. I also learned how if something is raised to an even exponent, the answer has to have a plus/minus.]]> 2018-09-28 14:17:35 UTC https://padlet.com/9956845/2tov7w6loflu/wish/286967067 The end behavior for y=x^-2 is "as x approaches infinity, y approaches 0 9956845 https://padlet.com/9956845/2tov7w6loflu/wish/296930949 This "volcano" graph looks like this because the equation does not allow you to use 0, because in this equation, it is not a real number. The graph will just keep  getting closer and closer to the x axis because the equations provides points on the graph that keep getting closer and closer, but never actually tough the x axis because 0 does not exist in this equation. Or in other words, it is not a real number.]]> 2018-10-25 13:41:52 UTC https://padlet.com/9956845/2tov7w6loflu/wish/296930949 Self-evaluation 9956845 https://padlet.com/9956845/2tov7w6loflu/wish/306374975 The first part of this year has definitely been a struggle. I was good at Algebra 1 and Geometry, but Algebra 2 seems much much harder. Some things that I'm happy about are my ability to problem solve when doing problems that I do not know how to do. Some areas that I need to work on are asking for help and learning how to understand what exactly we are working on in class. I plan on changing my study habits. I'm just not completely understanding the material that we are learning in class.]]> 2018-11-20 14:55:13 UTC https://padlet.com/9956845/2tov7w6loflu/wish/306374975 Modeling 9956845 https://padlet.com/9956845/2tov7w6loflu/wish/306380394 To model a situation, you are usually given a graph and you need to find the best fit equation. I still don't understand how you know which equations to use for which situations.]]> 2018-11-20 15:04:56 UTC https://padlet.com/9956845/2tov7w6loflu/wish/306380394
