Entering f(x) notation in NEW CAS app
In the new CAS app (Sep 4, 2019), the tutorial indicates that entering a function with f(x) notation should generate a graph in the graphics window...it does not. After the function is entered in f(x) notation the tutorial indicates that you should be able to perform various operations on the function using the function name (like evaluating the function with specific input values, taking limits of the function, derivatives, etc), but without being able to have the f(x) notation recognized by the app, these operations are not available. Am I missing something? I am able to enter a function with "y=" notation and then label the function as "f". This will generate a graph, and allow me to find the roots of the function, but none of the other function operations (Limits, Derivatives, etc).
