The relation {(cat, 1), (dog, 5), (cat, 6), (chicken, 9)} is not a function, because there are two ordered pairs with the same first element, "cat" - (cat, 1) and (cat, 6). In a function, each input (first element) must correspond to only one output (second element).
The relation { (a,10), (b, 11), (-a, 12), (c,13)} is also not a function, because the input "-a" and "a" have different outputs (12 and 10, respectively). In a function, each input must correspond to only one output.
A function is a relation between a set of inputs and a set of possible outputs with the property that each input is associated with exactly one output. In other words, for each input, there is only one output.
The concept of functions is important in many areas of mathematics and its applications, such as physics, engineering, and computer science. Functions can be represented using various mathematical notations, such as tables, graphs, or algebraic formulas.

There are 1.3 miles in 2,200 yards.
It is the conversion of one unit to another unit with its standard conversion.
Examples:
1 hour = 60 minutes
1 minute = 60 seconds
1 km = 1000 m
We have,
2,200 yards ____(1)
1 mile = 1760 yards _____(2)
Now,
From (1) and (2),
1 mile = 1760 yards
Multiply 2,200/1760 on both sides.
2,200/1760 x 1 mile = 2,200/1760 x 1760 yards
1.25 miles = 2,200 yards
Rounding to the nearest tenths.
1.3 miles = 2,200 yards
Thus,
There are 1.3 miles in 2,200 yards.

Answer:
1.25 mi
Step-by-step explanation:
First, we want to convert a yard into feet; recall 1 yard = 3 feet.
Then we want to divide that by the number of feet in a mile 1 mile = 5280feet.
So 2200*3 =6600, then divide by 5280
6600/5280 = 1.25 mi
2200 yard is 1.25 miles
