9. according to the 2016 us census, 7 out of every 25 homes are heated by electricity.
at this rate, predict how many homes in a community of 12000 would be heated by
electricity

B

Step-by-step explanation:

h(t) = (t + 3)² + 5

A) h(t) = (t + 3)² + 5      -2 ≤ t ≤ 0

average rate of change in h over the change in t is given as:

It does not have a negative average rate of change

B) A) h(t) = (t + 3)² + 5      -4 ≤ t ≤ -3

average rate of change in h over the change in t is given as:

It have a negative average rate of change

c) A) h(t) = (t + 3)² + 5      -3 ≤ t ≤ 4

average rate of change in h over the change in t is given as:

It does not have a negative average rate of change

D) h(t) = (t + 3)² + 5      1 ≤ t ≤ 4

average rate of change in h over the change in t is given as:

It does not have a negative average rate of change
