An architect is designing a water fountain for a park she uses the given function to model the water jets flowing from the fountain nozzles where HX gives the height of the water jet in feet X feet from its starting point select two adjacent columns that show an interval with an average rate of change of -0.3

  columns with x=12, x=14

Step-by-step explanation:

The average rate of change is given by ...

  (h(x2) -h(x1))/(x2 -x1)

We want this to be -0.3. We observe that adjacent columns have x2-x1 = 2, so we want ...

  -0.3 = (h(x2) -h(x1))/2

  -0.6 = h(x2) -h(x1)

  h(x2) = h(x1) - 0.6

The two columns that have this relationship are shown below.
