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)

It will be 3:45. You can find this by going ahead 3 hours, then going ahead a half an hour.
Answer:
it decreased by 40%
Step-by-step explanation:
Answer:
infinite solutions
x is all real numbers
Step-by-step explanation:
2x+1+x=3(x-2)+7
Distribute
2x+1 +x = 3x -6+7
Combine like terms
3x+1 = 3x+1
Subtract 3x from each side
3x-3x+1 = 3x-3x+1
1=1
This is always true, so it doesn't matter what value we put in for x
X is all real numbers
