We conclude that the relation presented in the picture is a function with domain: - 4 ≤ x < 1 and range: - 4 ≤ x ≤ 5. (Correct choices: B, C, H)
<h3>How to determine the domain and range of a relation and if a relation is a function</h3>
Herein we have a relation between two variables, x and y, relations involve two sets: an input set called domain and an output set called range. A relation is a function if and only if every element of the domain is related to only one element from the range.
Graphically speaking, the horizontal axis corresponds with the domain, whereas the vertical axis is for the set of the range. According to the previous concepts, we conclude that the relation presented in the picture is a function with domain: - 4 ≤ x < 1 and range: - 4 ≤ x ≤ 5. (Correct choices: B, C, H)

D. After 150 minutes, the 5 cent one is more.
Hope this helps!
Answer:
B. 10 ft by 12 ft
Step-by-step explanation:
The perimeter is the length of all the sides added. Because it's a rectangle there are two pair of parallel lines. 10+10=20
12+12=24
24+20=44
118.2 Degrees is the correct answer.
Further Explanation:
The diagram is attached with the answer to explain the scenario.
We can see that ∠1 and ∠2 are supplementary angles i.e. their sum will be 180°
So,
m∠1 + m∠2 = 180°
61.8° + m∠2 = 180°
m∠2 = 180° - 61.8°
m∠2 = 118.2°
Corresponding angles are those angles which have the same relative position on each intersection where a line intersects two other lines. If the two other lines are parallel then corresponding angles are equal.
We can see from the diagram that ∠2 and ∠6 have the same realtive position and as the lines which were intersected are parallel so
m∠2 = m∠6
So,
m∠6 = 118.2°
