So for something to be continuous at x equals zero, let's think about what has to happen. So if I have a function here, so that is my x-axis, and let's say this is my y-axis, and we care about what happens at x equals zero. So x equals zero there, and let's say that this is our function. Let's say that this is our function. So maybe our function maybe looks something like this. I don't know what, well, this one in particular probably looks something like this. This one in particular, this one in particular might look, who knows, and then it might look something like that.
