A graph, origin O, with grid. Horizontal axis, x, scale from negative 5 to 5. Vertical axis, y, scale from negative 5 to 5. A u-shaped curve is drawn, opening to the right, passing through the points 0 comma negative 2, negative 4, comma 0, and 0 comma 2.
3.2
Activity
A graph, representing the function , has these points. Write each of these coordinate pairs in function notation.
A function is given by the equation . Given values in function notation, write the coordinate pair for the point on the graph associated with each of those values.
3.3
Activity
Draw a graph of a function that has these properties:
is on the graph
Han draws this graph for . What is the error?
A coordinate plane, with grid. The horizontal axis, x, scale from negative 10 to 10 by 1s. The vertical axis, y, scale from negative 10 to 10, by 1s. Three line segments are drawn on the graph. One has endpoints at 0 comma 2 and 1 comma 3. Another has endpoints at 0 comma 2 and 2 comma 3. Another has endpoints at 0 comma 2 and 5 comma negative 1.
