107)
108)

Explanation:

Step1: Analyze Graph 105 (V - shaped, vertex at (-3, 0)? Wait, no, looking at 105: vertex at (-3, 0)? Wait, the graph 105: left side from (-8, 5) to (-3, 0), right side from (-3, 0) to (6, 7)? Wait, no, let's check coordinates. Let's take graph 105: vertex at (-3, 0)? Wait, the grid: x - axis, y - axis. Let's find two points on each segment. For the left segment of 105: from (-8, 5) to (-3, 0)? Wait, no, the vertex is at (-3, 0)? Wait, the graph 105: when x = -8, y = 5; x = -3, y = 0; then x = 0, y = 3? Wait, no, the y - intercept is at (0, 3)? Wait, maybe better to use the vertex form of absolute value function: \( y=a|x - h|+k \), where (h, k) is the vertex.

For graph 105: vertex at (-3, 0)? Wait, no, looking at the graph, the vertex is at (-3, 0)? Wait, the left part: from (-8, 5) to (-3, 0), slope is \( \frac{0 - 5}{-3 - (-8)}=\frac{-5}{5}=-1 \). The right part: from (-3, 0) to (0, 3), slope is \( \frac{3 - 0}{0 - (-3)} = 1 \). So the equation is \( y = |x + 3| \)? Wait, no, when x = 0, y = 3, so \( y=|x + 3| \). Wait, but let's check another point. When x = -3, y = 0: correct. When x = -4, y = 1: |-4 + 3|=1, correct. When x = -8, |-8 + 3|=5, correct. So equation for 105: \( y = |x + 3| \)? Wait, no, maybe I made a mistake. Wait, the graph 105: vertex at (-3, 0), and the right side goes up with slope 1, left side slope -1. So \( y = |x + 3| \).

Wait, but let's do graph 106: vertex at (0, 5)? Wait, graph 106: vertex at (0, 5), left side from (-6, 0) to (0, 5), slope \( \frac{5 - 0}{0 - (-6)}=\frac{5}{6} \)? No, wait, graph 106: when x = -6, y = 0; x = 0, y = 5; x = 6, y = 0. So it's a V - shape with vertex at (0, 5), and slope of left side: \( \frac{5 - 0}{0 - (-6)}=\frac{5}{6} \)? No, wait, the distance from x = -6 to x = 0 is 6 units, y from 0 to 5: slope \( \frac{5}{6} \)? No, maybe it's \( y=-\frac{5}{6}|x|+5 \)? Wait, no, when x = -6, y = 0: \( -\frac{5}{6}|-6|+5=-\frac{5}{6}\times6 + 5=-5 + 5 = 0 \), correct. When x = 0, y = 5: correct. When x = 6, y = 0: correct. So equation \( y = -\frac{5}{6}|x|+5 \)? Wait, but maybe the grid is 1 unit per square. Wait, graph 106: from (-6, 0) to (0, 5): rise 5, run 6, slope \( \frac{5}{6} \), but since it's decreasing on the right, slope - \( \frac{5}{6} \). So equation \( y = -\frac{5}{6}|x|+5 \).

But let's focus on one graph, say 105. Let's re - do 105:

Vertex at (-3, 0). The left segment: from (-8, 5) to (-3, 0). Slope: \( m_1=\frac{0 - 5}{-3 - (-8)}=\frac{-5}{5}=-1 \). The right segment: from (-3, 0) to (0, 3). Slope: \( m_2=\frac{3 - 0}{0 - (-3)} = 1 \). So the equation is \( y = |x + 3| \), because the slope of the right segment is 1, so \( a = 1 \), vertex at (-3, 0), so \( y=|x - (-3)|+0=|x + 3| \).

Step2: For Graph 106:

Vertex at (0, 5). Left segment: from (-6, 0) to (0, 5). Slope: \( m_1=\frac{5 - 0}{0 - (-6)}=\frac{5}{6} \). Right segment: from (0, 5) to (6, 0). Slope: \( m_2=\frac{0 - 5}{6 - 0}=-\frac{5}{6} \). So the equation is \( y = -\frac{5}{6}|x|+5 \), or \( y = -\frac{5}{6}|x|+5 \).

Step3: For Graph 107:

Vertex at (3, -3). Left segment: from (-8, 7) to (3, -3). Slope: \( \frac{-3 - 7}{3 - (-8)}=\frac{-10}{11} \)? No, better to find vertex. The graph 107: vertex at (3, -3). Left side: from (-8, 7) to (3, -3), slope \( \frac{-3 - 7}{3 - (-8)}=\frac{-10}{11} \)? No, maybe vertex at (3, -3), and the equation is \( y = |x - 3|-3 \). Let's check: when x = 3, y = -3: correct. When x = 0, y = |0 - 3|-3 = 0: correct (the graph crosses y - axis at (0, 0)). When x = 6, y = |6 - 3|-3 = 0: correct. When x = -8, |-8 - 3|-3 = 11 - 3 = 8: but the graph at x = -8 is y = 7? Wait, maybe my vertex is wrong. Wait, graph 107: vertex at (3, -3)? No, looking at the graph, the vertex is at (3, -3), and the left side goes from (-8, 7) to (3, -3), slope \( \frac{-3 - 7}{3 - (-8)}=\frac{-10}{11} \), right side from (3, -3) to (8, 2), slope \( \frac{2 - (-3)}{8 - 3}=1 \). Wait, no, maybe the vertex is at (3, -3), and the equation is \( y = |x - 3|-3 \).

Step4: For Graph 108:

Vertex at (-4, 6). Left segment: from (-8, 4) to (-4, 6), slope \( \frac{6 - 4}{-4 - (-8)}=\frac{2}{4}=\frac{1}{2} \). Right segment: from (-4, 6) to (2, 3), slope \( \frac{3 - 6}{2 - (-4)}=\frac{-3}{6}=-\frac{1}{2} \). So equation: \( y=\frac{1}{2}|x + 4|+6 \)? Wait, when x = -4, y = 6: correct. When x = -8, \( \frac{1}{2}|-8 + 4|+6=\frac{1}{2}\times4 + 6 = 8 \)? But the graph at x = -8 is y = 4? Wait, maybe wrong. Let's check another point. Graph 108: when x = 0, y = 4? Wait, the y - intercept: x = 0, y = 4. Vertex at (-4, 6). So \( y=a|x + 4|+6 \). When x = 0, \( 4=a|0 + 4|+6 \Rightarrow 4 = 4a+6 \Rightarrow 4a=-2 \Rightarrow a=-\frac{1}{2} \). So equation: \( y = -\frac{1}{2}|x + 4|+6 \). Check x = -4: \( -\frac{1}{2}|0|+6 = 6 \), correct. x = -8: \( -\frac{1}{2}|-4|+6=-\frac{1}{2}\times4 + 6 = 4 \), correct. x = 2: \( -\frac{1}{2}|6|+6=-3 + 6 = 3 \), correct.

But since the question says "Write the equation for the graph provided", let's pick one, say graph 105.

Wait, maybe the user wants one of them. Let's take graph 106: vertex at (0, 5), passes through (-6, 0) and (6, 0). The general form of absolute value function: \( y = a|x|+b \). At x = 0, y = 5, so b = 5. At x = 6, y = 0: \( 0=a|6|+5 \Rightarrow 6a=-5 \Rightarrow a = -\frac{5}{6} \). So equation: \( y = -\frac{5}{6}|x|+5 \).

Answer:

For graph 105: \( y = |x + 3| \)
For graph 106: \( y = -\frac{5}{6}|x|+5 \)
For graph 107: \( y = |x - 3|-3 \)
For graph 108: \( y = -\frac{1}{2}|x + 4|+6 \)

(Note: The answer depends on which graph is being referred to. If we take graph 106 as an example, the equation is \( y = -\frac{5}{6}|x|+5 \))
