graph of (-2)^x Hey, Just for fun... I'm trying to see what a graph of y=(-2)^x would look like. It would seem that y=would be undefined for all non whole numbers ...I think. I see some kind of an increasing wave. or something… dan |

Re: graph of (-2)^xDan, Antoher excellent question. Since you can't really get the graph in the usual way, you can take a look at two "similar" graphs: y=2^x and y=-(2^x) The actual graph of y=(-2)^x, when it is defined as a real number, lies on one of these graphs. Of course, it takes "discrete" values on these two curves. That's a good way to look at this! Thanks for asking this question. ---------------------------------------- Principal Skinner |
