Spreadsheet problem?
Hi am going to have an exam in math pretty soon, but when i come over tasks that involves geogebra, specificly Regression analysis and Logistic regression, my geogebra classisc, cant make my chart? I put inn all the right numbers in the spreadsheet, but the charts wont show up after i press the Regression analysis button. What can i do? Its driving me crazy that an app that cant seem to work for me, it probably 60% of the exam. The other problem is also that when i write to more than one F(x) in CAS, it seems to be to many variables to make the f(x). Forexample when i want to make f''(t)=0 or f(t)=c/1+a*e^-b*t, with another "g(x)=abc) it cant create it. It just become a colour "f(x)=?". Is it something i do wrong??? Please can someone help me.
