Answer:
If you count by 2's and 2 x 2 = 4
Step-by-step explanation:
A sneaker company can make 50 pairs of sneakers for every 6 yards of material.
Then in each case you can consider proportion.
1. 50 pairs -- 6 yards,
80 pairs -- x yards.
Mathematically,
2. 50 pairs -- 6 yards,
100 pairs -- x yards.
Mathematically,
3. 50 pairs -- 6 yards,
120 pairs -- x yards.
Mathematically,
4. 50 pairs -- 6 yards,
140 pairs -- x yards.
Mathematically,
Thus, the table is
The domain of the relation is the set 
and the range of the relation is 
See attached diagram for the graph of the relation.
By understanding and applying the characteristics of <em>piecewise</em> functions, the results are listed below:
- r (- 3) = 15
- r (- 1) = 11
- r (1) = - 7
- r (5) = 13
<h3>How to evaluate a piecewise function at given values</h3>
In this question we have a <em>piecewise</em> function formed by three expressions associated with three respective intervals. We need to evaluate the expression at a value of the <em>respective</em> interval:
<h3>r(- 3): </h3>
-3 ∈ (- ∞, -1]
r(- 3) = - 2 · (- 3) + 9
r (- 3) = 15
<h3>r(- 1):</h3>
-1 ∈ (- ∞, -1]
r(- 1) = - 2 · (- 1) + 9
r (- 1) = 11
<h3>r(1):</h3>
1 ∈ (-1, 5)
r(1) = 2 · 1² - 4 · 1 - 5
r (1) = - 7
<h3>r(5):</h3>
5 ∈ [5, + ∞)
r(5) = 4 · 5 - 7
r (5) = 13
