Well there are 5280 feet in 1 mile and if you multiply that by 2 then that's too many. if you multiply 5280 by 1.5, then you get 7920 so it is equal to 1.5 miles.
There are 36 inches in 1 yard so you multiply 6 by 36 to get 216.
Again there are 5,280 feet in 1 mile. Divide 26,400 by 5,280 and you get 50 miles.
12 inches in 1 foot. Multiply 12 by 9 and get 144.
22 feet equals 7 yards and 1 foot.
51 inches equals 4 feet and 3 inches. (4 feet equals 48 inches)
Btw, 7 yards is greater then 20 feet (7 yards equals 21 feet)
2 miles is more then 3,500 yards. (2 miles equals 2,520 yards)
11.5 feet is less then 4 yards (4 yards equals 12 feet)
72 inches is EQUAL to 2 yards
5.5 yards is more then 192 inches. (5.5 yards equals 198 inches)
Imagine that this curve is a roller coaster. A dot on the roller coaster would be a car for a person to sit in, so to speak. As this car moves to the right, the car ultimately moves downward. So this means that as x gets larger, y gets smaller. Put another way: as x approaches infinity, f(x) approaches negative infinity.
Similarly, we can move the other way to work our way to the left. Moving to the left has us go up this time. As x approaches negative infinity, f(x) approaches positive infinity
These two facts point to choice B as the final answer
