False, it's always on the vertex of the parabola.
Emily bikes 12 miles, generating a donation unit for every 0.75 miles. Her 12 mile ride will generate
12 × 0.75 = 9 donation units. For each of these 9 danation units her mother will donate 80 cents.
It follows that Emily's mom will donate
9 donation units × $0.80 per unit = $7.20.
1)
16.90 is about $17
$17 * 3 = 51
6.99 is about $7
7 * 4 = 28
28 + 51 = 79
This is not reasonable because it costs $79, which is more than $75.
7 * 3 = 21
21 + 51 = 72
The customer has enough for 3 supreme pizzas and 3 dessert pizzas.
2)
16.90 is about 17
5.99 is about 6
17 + 6 = 23
23 - 5 = 18
This is reasonable.
3)
14.85 is about 15
6.99 is about 7
15 + 7 = 22
22/100 = 0.22
0.22 * 22 = 4.84
This is reasonable.
4)
16.90 is about 17
14.85 is about 15
5.99 is about 6
6.99 is about 7
17 * 5 = 85
15 * 5 = 75
6 * 5 = 30
7 * 5 = 35
85 + 75 + 30 + 35 = 225
This is reasonable
5)
14.85 + 1.39(4) = 20
1.39 * 4 = 5.56
14.85 + 5.56 = 20.41
This is not reasonable because the total is more then $20.

One example is if a guy studied 8 hours a day and score 75 marks and another studied 8 hours and scored 95 marks.
<h3>What are relations and functions? </h3>
A function is a relation that states that each input should have only one output (or) a special type of relation (a collection of ordered pairs) that follows a rule, i.e., every X-value should be connected with only one y-value.
The Cartesian product is a subset of it. Alternatively, a collection of points (ordered pairs). In other words, the collection of the ordered pair is defined as the relationship between the two sets, where the ordered pair is generated by the object from each set.
One example of an everyday situation between relations that is not a function is if a guy studied 8 hours a day and score 75 marks and another studied 8 hours and scored 95 marks.
