Once.
Step-by-step explanation:
To find when they chirp together, we must find the LCM of the two numbers. The LCM, or least common multiple of 13 and 5 is 65. Therefore, after 65 minutes is the first time they chirp together. Then we can multiply 65 by 2 to see if they chirp a second time. 65x2 is 130, but 8AM-10AM is only 120 minutes, therefore they do not chirp together more than 1 time.
To find the domain and range is very simple. The domain will always be the input values or x values. For example ( 3,0) the domain is 3 being the x value. The range is the output value or y value and in the example (3,0) the range is 0. Hope this helps :)
