Question

Must a function that is decreasing over a given interval always be negative over that same interval? Explain. This is the question. Can someone please help explain the question and answer?

Answer 1

well Clearly, this function is decreasing and negative over its domain. This function is decreasing over the interval. but it is not negative. so the function may not be negative over the interval it is decreasing on.

Answer 2

Sample Response: For a function to be decreasing over an interval, the outputs on the function are getting smaller as the inputs of the function are getting larger, but the outputs could be positive or negative. For a function to be negative over an interval, the outputs must be negative, while the inputs could be positive or negative.
