Then since A equals zero, this would not be a straight line, it'd be some other line. And that means we can conclude that our A is not one, our A must be something else. And in order to determine A equals zero, we have to actually graph what we graphed before and after we graph. If we got a straight negative line, we can conclude that our A equals zero. So finally, let's look at the graph for A equals two. So what will the graph look like when our exponent is two?
