Serge made the following conjecture: when 3 is subtracted from a perfect square that is greater than 4, the result is always a composite number. For example: 15^2 - 3 =222. 222 is a composite number because it is divisible by factors other than 1 itself. Do you agree with Serge’s conjecture? Justify your decision.

Consider the functions below. function 1 function 2 function 3 select the statement which is true about the functions over the interval [1, 2] a b function 3 has the highest average rate of change function 2 and function 3 have the same average rate of change. function and function 3 have the same average rate of change function 2 has the lowest average rate of change d.
