Use the graph of at right to determine the following values.

  1. Find the point on the function that has an -value equal to the input. Its y-value will equal the output.

    Added to the graph, a point at (1, comma negative 1).

  1. Added to the graph, a point at (negative 6, comma 2).

A piecewise graph: A ray starting at the point (negative 3, comma negative 2) & going up & left through the point (negative 4, comma 0). Part of a downward parabola starting at (negative 3, comma negative 2) increasing to a vertex at (negative 2, comma 1), and decreasing to the point (negative 1, comma negative 1). Part of an upward parabola decreasing from (negative 1, comma negative 1) to the vertex (0, comma negative 2) &, increasing through (1, comma negative 1) & continuing to increase.
