MY NOTES PRACTICE ANOTHER Find the horizontal and vertical asymptotes of the curve. y = 1+x4 x2 - x4 X = -1 (smallest x-value) X = 0 X = 1 V (largest x-value) y = 3 X Enhanced Feedback :Please try again. For finding the horizontal asymptotes, find the limits of the function as x approaches . or - co. For finding the vertical asymptotes, look for numbers at which you are dividing by zero. Evaluate the limits as x approaches these numbers to check that they are asymptotes
