Graph: f(x) = -1/(x - 3) + 1
This becomes a hyperbola with asymptotes at: x = 3 and y = 1.
Since the coefficient of the x-term is negative, it will graph in the upper-left and lower-right portions of the plane separated by the asymptotes.
As the values for x get very large, the y-values approach 1 from below.
As the values for x get very small (large negative), the y-values approach 1 from above.
As the values for x approach 3 from the left, the values for y go to positive infinity.
As the values for x approach 3 from the right, the values for y go to negative infinity.
