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

${2}^{(5x + 3)} = \frac{1}{128} \\ {2}^{(5x + 3)} = \frac{1}{ {2}^{7} } \\ {2}^{(5x + 3)} = {2}^{ (- 7)} \\ 5x + 3 = - 7 \\ 5x = - 7 - 3 \\ 5x = - 10 \\ x = \frac{ - 10}{5} \\ \boxed{x = - 2}$

x = -2 is the right answer.
