Where the others get shorter with larger numbers, interval gets longer. Your best bet is to set it to normal then calculate what % of that time you want. Set that % of 1 as the interval value. IE if interval is normally 1 hour, .5 interval will change that to 30 min.As the ball traces the curve from left to right, identify intervals using "interval notation" as either increasing or decreasing. f x = x x − 2 x + 4 x − 4 x + 4. a = −5.44.Percentage increase/decrease calculation. The percentage increase/decrease from old value (V old) to new value (V new) is equal to the old and new values difference divided by the old value times 100%: percentage increase/decrease = (V new - V old) / V old × 100%. Example #1. Price percentage increase from old value of $1000 to new value of ... Poops did seem to be messing with the egg drop rate. Turned the poop interval back up to 0.5 and the eggs were more frequent (with the same egg drop interval). So if you were trying to increase egg *and* poop production, it would seem keeping the poop interval larger than the egg interval is the way to go.If the slope (or derivative) is positive, the function is increasing at that point. If it’s negative, the function is decreasing. So to find intervals of a function that are either decreasing or increasing, take the derivative and plug in a few values.
