The discriminant of this quadratic is b2 - 4 ac = 6 2 - 4*2*5 = 36 - 40 = -4. Since the discriminant is negative, N ( x ), and consequently f ( x ), has no real roots. The graph never crosses the x -axis. WebTo find oblique asymptotes, the rational function must have the numerator's degree be one more than the denominator's, which it is not. So, there are no oblique asymptotes. … can i backup my computer to google drive
