I struggled with math growing up and have been able to use those experiences to help students improve in math through practical applications and tips. degree of numerator = degree of denominator. The distance between the curve and the asymptote tends to zero as they head to infinity (or infinity), as x goes to infinity (or infinity) the curve approaches some constant value b. as x approaches some constant value c (from the left or right) then the curve goes towards infinity (or infinity). y =0 y = 0. If the degree of the polynomial in the numerator is equal to the degree of the polynomial in the denominator, we divide the coefficients of the terms with the largest degree to obtain the horizontal asymptotes. Applying the same logic to x's very negative, you get the same asymptote of y = 0. Find the vertical asymptotes by setting the denominator equal to zero and solving for x. How many whole numbers are there between 1 and 100? Since the degree of the numerator is smaller than that of the denominator, the horizontal asymptote is given by: y = 0. The horizontal asymptote identifies the function's final behaviour. i.e., apply the limit for the function as x -.
