I'm working on a project for my math class. We need to make an image on our calculators (Texas Instruments) using the
DrawF function (which graphs functions as
y=). I need an exponential function that starts below zero. From what I understand, they can't (according to my Algebra II textbook and a few Google searches).
Is it possible to draw the line I need with an exponential?
Side note: I would rather use this than, say, mushing it together with other types of equations because we need at least two exponential functions, and I can't find a better place to use them.
