"When the storm began", it means it has been snowed for 0 hours, so n=0.
f(0)=2.5, thus the <span>depth of snow was 2.5 inches when the storm began.
f(n+1)=f(n)+0.8, so f(n+1)-f(n)=0.8
it means when the time increases by one hour, the depth of snow increases by 0.8 inches.</span>
A solid line means either ≥ or ≤
So either A or B
Above the graph: Must be greater than y
B
The correct answer for this statement would be FALSE. Let us try to prove it by plugging in the values. So 2 (1/2) - 3 (1/3) <span> ≥ 5.
So that would be 1 - 3 </span><span> ≥ 5..
-2 </span><span> ≥ 5, which makes the result false because -2 is not more than or equal to 5, but instead, it is less than. I hope this answer helps. </span>
