## ValentinaT 2 years ago Help with finding asymptotes and graphing rational functions?

talki to @DrPepperx3 I thin she's doing the same problems

3. Jhannybean

These problems just have vertical asymptotes. To find a vertical asymptote take the function at the bottom and equal it to 0. When the denominator of a function equals 0, or does not exist, you have a vertical asymptote.

here is a site that helped me understand asymptotes http://www.purplemath.com/modules/asymtote4.htm

Okay, thanks! When I'm finished finding the asymptotes, could you help me with graphing them? If you don't mind.

6. Jhannybean

Sure, I can try

7. ValentinaT

Okay, thanks.

Okay, so I got: 36. x = -2, y = 0 37. x = -3, y = 0 38. x = 4, y = 1 39. x = 5, y = -1

So when you're graphing vertical asymptotes for problems 36-39, all you need to do is use your x-intercepts and draw a line that crosses them. a "vertical" asymptote will intersect only one x-value and it means that the function will come really close to that point but it will never cross it.

Okay, I finished graphing 36 - 39. Could you help me with 40?

welfor part b, i believe the intensity of the light wouldnt be as strong, considering you're further away from the light bulb.
