It satisfies the wave equation. You can check, by double differentiating it with x and t.

No its not complex exponential. And it requires infinite energy because at x --> infinity, the function tends to infinity. It's energy density increases with x. So it need to be supplied with energy for infinity.

We know that a wave is represented by f(x - vt) and it follows the differential wave equation. e^(x - vt) satisfies both the condition. But is it really a wave? Because to sustain the wave we need infinite energy which is not possible. So what's happening here?
