A) find the value of f(3)+f(6) b)state all intervals over which f(x)<0

c)state the zeroes of the function

d)give an interval over which f(x) is only decreasing

e)state the range of f(x)

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
