see the attached figures

Step-by-step explanation:

Part 1) we have

The vertex is the point (1,0)

The equation of the line of the left side is y=-x+1

The equation of the line of the right side is y=x-1

The range of the function is equal to $y\geq 0$

therefore

The absolute function will be equal to

$y=\left|x-1\right|$

see the attached figure N 1

Part 2) we have

The vertex is the point (0,1)

The equation of the line of the left side is y=x+1

The equation of the line of the right side is y=-x+1

The range of the function is equal to $y\leq 1$

therefore

The absolute function will be equal to

$y=-\left|x\right|+1$

see the attached figure N 2

Part 3) we have

The vertex is the point (1,-1)

The equation of the line of the left side is y=-x

The equation of the line of the right side is y=x-2

The range of the function is equal to $y\geq -1$

therefore

The absolute function will be equal to

$y=\left|x-1\right|-1$

see the attached figure N 3

Part 4) we have

The vertex is the point (-1,0)

The equation of the line of the left side is y=-x-1

The equation of the line of the right side is y=x+1

The range of the function is equal to $y\geq 0$

therefore

The absolute function will be equal to

$y=\left|x+1\right|$

see the attached figure N 4

Part 5) we have

The vertex is the point (-1,1)

The equation of the line of the left side is y=x+2

The equation of the line of the right side is y=-x

The range of the function is equal to $y\leq 1$

therefore

The absolute function will be equal to

$y=-\left|x+1\right|+1$

see the attached figure N 5

Answer from: Quest

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
