<h3>
Answer: Choice C. y = -|x-1| + 3</h3>
=========================================
Work Shown:
General form of absolute value equations
y = a|x-h| + k
The 'a' determines if the V shape is upside down or not. If a > 0, then we have a V shape that isn't upside down. If a < 0, then the V shape is upside down as this diagram shows. In this case, a = -1.
The (h,k) is the vertex of the graph. For upside down V shaped graphs, the vertex is the highest point, which is (1, 3) in this case.
(h,k) = (1,3)
h = 1 and k = 3
So,
y = a|x-h|+k
y = -1|x-1| + 3
y = -|x-1| + 3
