    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.

    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.
