Full solution stays hidden until you ask for it.
1. Use f(x)=a|x-h|+k from the vertex.
2. Use opening direction and arm slope to determine a.
3. Write the transformed absolute-value function.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
