explaining graphs of functions\nmust a function that is decreasing over a given interval always be negative over that same interval? explain.
Answer
Brief Explanations:
A decreasing function means the y - values decrease as x - values increase in an interval. But the function's values can be positive, negative or zero in that interval. For example, the function y = -x + 5 is decreasing on the interval (0, 5) and is positive in that interval.
Answer:
No, a function that is decreasing over a given interval does not always have to be negative over that same interval.
