thats not a system of equations, that is a solution
no oblique asymptote
to find the oblique asymptote of f(x)
here numerator has degree 1 and denomintor degree 2
degree of numerator < degree of denominator
hence there is no oblique asymptote
when the degree of the denominator > that of the numerator, we saw that the value in the denominator got so much bigger, so quickly, giving us a horizontal asymptote of the x-axis. or we can write
f(x) = a polynomial of x + a proper fraction.
in this case only we have oblique asymptotes but not when numerator has less degree.
