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 4 to 4. • The graph begins at negative 1 comma negative 1, then increases to 0 comma 0, and decreases to 1 comma negative 1. • From this point, the graph continues to increase and decrease by one unit moving left to right across the graph in a zig-zag pattern, ending at 11 comma negative 1. (1 point) Responses 1; –1 1; –1 1; 0.5 1; 0.5 2; 0.5 2; 0.5 0.5; 2
The period of the function is 2 (the distance between the peaks or troughs of the function). The amplitude of the function is 1 (half the distance between the maximum and minimum values of the function).
So, the correct response is: 2; 1
