What is the oblique asymptote of the function f (x) = (x^2 - 5x + 6) / (x - 4) ?

To determine the oblique asymptote of the function f (x), the numerator must have a greater order than the order of the order of the denominator. We can use long division to find the quotient which is the slant asymptote. in this case, the answer is x = 1
