This is the calculator that will be used on the SBAC test that all Juniors will take. And the “noise” we get here is a result of the algorithms TI calculators utilize to plot the points. This is a nice reminder that, while we may simplify a function, we are still looking at a quotient and need to consider the parent functions used in the division. Zoom in even more….doesn’t seem all that interesting…. Mathematics: Content Knowledge (5161) Algebra I (5162) Middle School. But what about x=-3? What happens there? Let’s explore a bit: The following tests provide an on-screen graphing calculator, the TI-84 Plus CE. Since the denominator is a factor of the numerator, we can simplify the expression, resulting in a linear function when we graph. features a virtual TI-84 Plus Silver Edition calculator that can be used on the test. We are interested in the rational function which comes from dividing the two previous functions: Desmos Online Graphing Calculator Texas/STAAR Edition Overview. This is a case where the Nspires are too nice for our use.Įnter functions as shown below.
