Use a quadratic function and an absolute value function to write a piecewise-defined function that will produce the graph shown below. Homework Help ✎

graph at right

Vertex form of a parabola: , where is the vertex. Absolute value: .

Solve for by evaluating both equations at .

Because the function for this graph is piecewise, there is an -coordinate / boundary point where each function ceases to defined.
