Date/Time Date(s) - Septem6:20 pm - 7:40 pm. I will go back to this post when i get time and see if i missed anything. You can also check that you have the correct inverse function beecause all functions. Personally I don’t find geogebra intuitive.
#Composite functions desmos activity full
To get more capability you have to download the full app. This exploration with composing functions leads students to the concept of inverse functions by noticing that for some functions f(g(x))g(f(x)) and that the line yx is produced by each composition. Geogebra has a browser supported graphing calculator as well but it seems to have limited capability and is geared more towards Euclidean constructions. I can’t wait when desmos offers full 3d graphing capability (and i dont mean those hacky 2d parametric curves which give the impression of depth, but that might be a way for desmos coders to wrap their heads around graphing 3d and start this project).ĭesmos is the best 2d browser supported graphing calculator, as far as ease of use, share-ability. This activity is designed for the students to discover the relationship between the transformtions of a graph and the parameters of the function of the graph. Wow… once again i am in awe of desmos capability.
My ultimate goal evolved into graphing the more general problem, (big thanks to eric for his code), without actually having to write out the explicit equation, namely rotating the parabola y = x^2 by the counterclockwise angle a, about the generic center of rotation (h,k), defined by the user and implemented by sliders (or entered manually).Īnd yes to find such an equation explicitly you would have to compose 4 functions which is a fun exercise.īy the way i was inspired to get that solution by this article, if you scroll down to ‘transformations’
