Question

Must a function that is decreasing over a given interval always be negative over that same interval? Explain.

Answer 1

 1)..f(x) = −2paw(x)
Clearly, this function is decreasing and negative.
2)..f(x) = 1 - xpaw(2)
here is also this func. is decreasing and negative but it's domain is 0<=x<=1...so the func. need not be negative over that same interval...it's maybe positive and decreasing or maybe negative for decreasing...

Answer 2

Answer: if you are on edgenuity

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.
