Answer:
C. Yes, because every x-value corresponds to exactly one y-value
Step-by-step explanation:
We are asked to find whether the given ordered pairs represent a function or not.
We know that a relation is a function, when each input of x value gives exactly one output of y-value.
In a function two or more x-coordinates can give same y-value, but one x-value cannot give two y-values.
We can see that in our given set each x-value corresponds to exactly one y-value, therefore, the given set represents a function.

Step-by-step explanation:
Wire is 4 1/2 feet, or 4.5 feet.
Each smaller wire needs to be 1 1/4 feet, or 1.25 feet.
<em>How many whole 1.25 feet wire can we have from total of 4.5 feet wire?</em>
<em />
Let's divide:
\
<em>thus we can have 3 whole "1.25 feet long" wire and fractional amount.</em>
<em />
<em>Hence, maximum number of smaller pieces is 3</em>
