A graphing calculator can find the zeros of the exponential function ...

  y = 6^(2n+1) +6^2 -6^n -6^(n+3) . . . . . right side subtracted

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"
