A graph of the transformed absolute value function h(x) = -|x + 2| + 3 and its pre-image is shown in the picture below.
In Mathematics, the vertex form of the equation for an absolute value function can be modeled by the following:
y = a|x - h| + k.
Where:
- h and k are the vertex of the graph.
- a is a numerical constant.
By critically observing the equation of the transformed absolute value function, we can logically deduce that the parent absolute value function g(x) = -|x| was horizontally shifted to the left by 2 units, followed by a reflection in the x-axis, and then vertically shifted 3 units up as follows;
g(x) = a|x - h| + k.
h(x) = -g(x + 2) + 3
h(x) = -|x + 2| + 3
