Math Problem Statement
so when you graph, Graph h(x)=-|x -6|+3, the 6 would be positive right?
Solution
Yes, when graphing the function , the value 6 inside the absolute value function corresponds to a horizontal shift. Specifically, it shifts the graph 6 units to the right, making the point of symmetry or the vertex.
Here’s how it breaks down:
-
Equation breakdown:
- The equation is in the form .
- , which shifts the graph 6 units to the right.
- , which shifts the graph 3 units upwards.
-
Vertex:
- The vertex of the graph will be at .
-
Reflection:
- The negative sign in front of the absolute value indicates a reflection across the x-axis. So instead of the usual V-shape opening upwards, the graph will open downwards.
In conclusion, the 6 inside does indicate a horizontal shift to the right, making it a positive shift, while the graph opens downward due to the negative sign in front of the absolute value.

Tip:
The horizontal shift is always opposite in sign to the value inside the absolute value. If you see , it means a shift to the right by 6 units.
