A confidence interval for a difference between means is a range of values that is likely to contain the true difference between two population means with a certain level of confidence. The formula to calculate the confidence interval is: Confidence interval = ( x1 - x2) +/- t*√ ( (s p2 /n 1) + (s p2 /n 2 ))This problem has been solved!

Step 2: Take the derivative of f ′ ( x) to get f ″ ( x). Step 3: Find the x values where f ″ ( x) = 0 or where f ″ ( x) is undefined. We will refer to these x values as our provisional inflection points ( c ). Step 4: Verify that the function f ( x) exists at each c value found in Step 3.

A critical point is when the derivative equals 0. And while it is always negative where you indicated, the derivative itself is increasing at one point. A much easier example to see this is -x^2. if this were the derivative of something, this also has a critical point at (0,0).Possible Answers: Correct answer: Explanation: To find the increasing intervals of a given function, one must determine the intervals where the function has a positive first derivative. To find these intervals, first find the critical values, or the points at which the first derivative of the function is equal to zero.Calendar Generator – Create a calendar for any year.

A positive f " ( x) indicates the function is concave up; the graph lies above any drawn tangent lines, and the slope of these lines increases with successive increments. A negative f " ( x) tells me the function is concave down; in this case, the curve lies ...Linear regression calculator. Linear regression is used to model the relationship between two variables and estimate the value of a response by using a line-of-best-fit. This calculator is built for simple linear regression, where only one predictor variable (X) and one response (Y) are used. Using our calculator is as simple as copying and ...Plug in a value that lies in each interval to the second derivative; if f '' (x) is positive, the function is concave upwards for that interval, and if f '' (x) is negative, the function is concave downwards for that interval. As a note, any point at which the function changes concavity is called a point of inflection. Some textbooks and ...

Determine where the cubic polynomial is concave up, concave down and find the inflection points. The second derivative of is .To determine where is positive and where it is negative, we will first determine where it is zero. Hence, we will solve the equation for .. We have so .This value breaks the real number line into two intervals, and .The second derivative maintains the same sign ...You then plug those nonreal x values into the original equation to find the y coordinate. So, the critical points of your function would be stated as something like this: There are no real critical points. There are two nonreal critical points at: x = (1/21) (3 -2i√3), y= (2/441) (-3285 …The concavity changes at points b and g. At points a and h, the graph is concave up on both sides, so the concavity does not change. At points c and f, the graph is concave down on both sides. At point e, even though the graph looks strange there, the graph is concave down on both sides – the concavity does not change.

That over this whole interval, g prime prime of x is less than zero, which means that over this interval we are concave downwards. So concave, concave downward, concave downward. Now let's go to the interval between negative one and one. So this is the open interval between negative one and one. And let's try a value there.
