You know when it is a periodic function if the values repeats in regular intervals or periods. An example of this is trigonometric functions that repeat over intervals of 2 pi radians.
To work this out you need to do 80 - 64 - 4.16 = 11.48
he received $11.48 change
The vertex would be (-2,4)
36 I believe sorry if it’s wrong what I did was multiply 2x 18 have I nice day good luck!
219-132 is the equation because the rest of the 219 comes from the girls who signed up. the answer is 77. To find how many more boys than girls signed up you need to subtract 77 from 132. 132-77= 55
