See Answer See Answer See Answer done loading. Question: 1. Find the intervals of increase and decrease for the function.We can plug these numbers into the Confidence Interval Calculator to find the 95% confidence interval: The 95% confidence interval for the true population mean weight of turtles is [294.267, 305.733] .Similarly, a function is decreasing on an interval if the function values decrease as the input values increase over that interval. The average rate of change of an increasing function is positive, and the average rate of change of a decreasing function is negative. Figure 3 shows examples of increasing and decreasing intervals on a function.Similarly, a function is decreasing on an interval if the function values decrease as the input values increase over that interval. The average rate of change of an increasing function is positive, and the average rate of change of a decreasing function is negative. Figure 3 shows examples of increasing and decreasing intervals on a function.If it's an increase, add the percentage to 100. If it's a decrease, subtract the percentage from 100. Because we're dealing with a decrease/discount, we'll subtract 100 - 75, giving us 25%. 4. Convert that number into a decimal. Do this by moving the decimal point two places to the left or dividing the number by 100.
0. If you have a function and there's an asymptote at say -7, then when doing the intervals for increase decrease, would you do something like increasing from (−∞, −7) ∪ (−7, wherever increase stops) ( − ∞, − 7) ∪ ( − 7, wherever increase stops) and not include the −7 − 7, or would the −7 − 7 be included. calculus ...The intervals of increasing are x in (-oo,-2)uu(3,+oo) and the interval of decreasing is x in (-2,3). Please see below for the concavities. The function is f(x)=2x^3-3x^2-36x-7 To fd the interval of increasing and decreasing, calculate the first derivative f'(x)=6x^2-6x-36 To find the critical points, let f'(x)=0 6x^2-6x-36=0 =>, x^2-x-6=0 =>, (x-3)(x+2)=0 The critical points are {(x=3),(x=-2 ... ….
