If a football player runs 5/6 of a mile every 3/4th of a hour, that means every 1/4th a hour he runs 1.5/6th of a mile.
That means every 15 minutes the football player runs .2 of a mile. That means that every hour he runs :
0.8 of a mile!

and
If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up (+1).
If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down (no change).
Answer:
B. [3, 5]
Step-by-step explanation:
The range of a graph are the y-values that are plotted on the vertical axis (y-axis). In order words, the range values, are the possible set of output values of that are plotted on the vertical axis on the graph.
"[ ]" is usually used to denote the possible set of values.
Therefore, the range of the given graph, as we can see from the y-axis, include values from 3 to 5. Therefore, the range of the graph is [3, 5].
Y(0)=0+3=3 (0;3)
y(1)=1+3=4 (1;4)
y(2)=2+3=5 (2;5)
x+3=0
x=-3
x+3=1
x=-2
x+3=2
x=-1
