A
Image with description On a coordinate plane, the scale on the x and y axes ranges from negative 7 to 3 in increments of 1. The graph represents the shifted absolute value function. The V-shaped graph is facing up. The vertex is at (negative 3 comma negative 2), and the function passes through (negative 7 comma 0) and (1 comma 0).
B
Image with description On a coordinate plane, the scale on the x and y axes ranges from negative 3 to 7 in increments of 1. The graph represents the shifted absolute value function. The V-shaped graph is facing down. The vertex is at (3 comma 2), and the function passes through (negative 1 comma 0) and (7 comma 0).
C
Image with description On a coordinate plane, the scale on the x and y axes ranges from negative 7 to 3 in increments of 1. The graph represents the shifted absolute value function. The V-shaped graph is facing down. The vertex is at (negative 3 comma negative 2), and the function passes through (negative 5 comma negative 3) and (negative1 comma negative 3).
D
Image with description On a coordinate plane, the scale on the x and y axes ranges from negative 2 to 8 in increments of 1. The graph represents the shifted absolute value function. The V-shaped graph is facing up. The vertex is at (3 comma 2), and the function passes through (negative 1 comma 6) and (7 comma 6).
