1.Use the given graph to determine the period of the function.
A. 4 B. -2.5 C. 2 D. 8
For questions 2 and 3, determine whether the function is periodic. If it is, find the period. A. periodic; about 6 B. periodic; about 3 C. periodic; about 12 D. not periodic
A. periodic; about 3 B. not periodic C. periodic; about 2 D. periodic; about 1 1/2
4. Find the period and the amplitude of the periodic function.
A. 1; -1 B. 1; 0.5 C. 2; 0.5 D. 0.5; 2
5. the screen below shows the graph of a sound recorded on an oscilloscope. What are the period and the amplitude? (Each unit on the t-axis equals 0.01 seconds.)
A. 0.05 seconds; 4.5 B. 0.05 seconds; 9 C. 0.025 seconds; 9 D. 0.025 seconds; 4.5
