What would the graph of y=kx^n look like is n is negative and even?

This graph would look like a hyperbola, with the exception that both parts of the graph are pointing upward in the positive y-direction in quadrant 1 and 2. The example of f(x) = kx^n (k=255, n=-4) is shown below. Increasing k has the effect of stretching the graph away from the y-axis. Decreasing n has the effect of pushing the graph towards the y-axis.
