write a piece-wise function over 3 intervals whose domain is (-infinity, infinity) and whose range is (-infinity,-3) united (1,10). include an increasig, decreasing, and a constant function.
Coming up with these is difficult, but working with these is not. Do you know what the domain and the range are, for starters? Have you ever seen this notation before? I have never seen the word united in this sense before. Do you know how to determine when a function is increasing, decreasing, or remaining the same?
