Vertical and Horizontal Asymptotes:
Using these will help with graphing. In this problem we are given y=1/x+4 to graph. To find the vertical asymptote, the denominator needs to equal zero and then solve for x. To find the horizontal aymptote, you multiply the function with 1/x over 1/x. * if the function is "x^2" then you multiply the function with 1/x^2 over 1/x^2. After you multiply, you must see if the absolute value of x approaches infinity. This helps you find the horizontal aysmptote. |
