I hope you're not trying to find the x-intercpt of y=3^x.
I'm working with a TI85, so it might be a tad different, but that should work. y1=3^x will get you a graph.
I'm having trouble seeing how to get the x intercept (assuming it were an equaion with an x intercept). Y intercept is easy. I'll see what I can figure out.
