Solution: By observing the intervals of the above graph, we can understand the points below: The function is increasing at interval 1 because as time increases, the distance traveled by Jim from home also increases.
WebEssentially, we have proved that the part of the function defined by 𝑓 of 𝑥 equals two 𝑥 plus 28 is always increasing. And so, our function is increasing over the open interval from negative ∞ to zero. Similarly, it’s decreasing for values of 𝑥 greater than zero. That’s the … WebSo f ′ ( x) = − 4 x ( x − 1) ( x + 1) will be a product of two positive numbers and a negative number, so f ′ ( x) is negative on ( − 1, 0). That means that f ( x) is decreasing on [ − 1, …
