Find the period and the amplitude of the periodic function. • The x axis extends from negative 1 to 11. • The y axis extends from negative 5 to 5. • The graph is formed by a series of line segments which begin at negative 1 comma negative 1, increases to 0 comma 0, then decreases to about 1 comma negative 4. • From this point, the graph decreases to 3 comma negative 1 and increases to about 4 comma 0. • The graph decreases to 5 comma negative 4, then increases to 6 comma 0. • The established pattern repeats, ending at 11 comma negative 1. (1 point) Responses 4; 2 4; 2 –4; 4 –4; 4 2; –4 2; –4 –4; 2
The period of the function is 4 and the amplitude is 2.
So the correct response is 4; 2.
