Question 7 (10 points) Given f (x) = (x - 2)2 (x - 4), determine a. interval where f (x) is increasing or decreasing, b. local minima and maxima off (x) c. intervals where f (x) is concave up and concave down, and d. the inflection points of f (x). Sketch the curve, and then use a calculator to compare your ...To determine whether a function is concave up or concave down using the second derivative, you can follow these steps: Find the second derivative of the function. This involves taking the derivative of the first derivative of the function. The second derivative is often denoted as f''(x) or d²y/dx². Identify the critical points of the function.Question: Consider the following. (If an answer does not exist, enter DNE.) f (x)=ex+9ex Find the interval (s) on which f is concave up. (Enter your answer using interval notation.) Find the interval (s) on which f is concave down. (Enter your answer using interval notation.) Find the inflection point of f. (x,y)= (. There are 3 steps to solve ...The fact that its derivative, \(f'\text{,}\) is decreasing makes \(f\) concave down on the interval. Figure \(\PageIndex{7}\). At left, a function that is concave up; at right, one that is concave down. We state these most recent observations formally as the definitions of the terms concave up and concave down.f (x)=3 (x)^ (1/2)e^-x 1.Find the interval on which f is increasing 2.Find the interval on which f is decreasing 3.Find the local maximum value of f 4.Find the inflection point 5.Find the interval on which f is concave up 6.Find the interval on which f is concave down. Anyone can explain? I know the f' (x)=e^-x (3-6x)/2 (x)^ (1/2) calculus. Share.The second derivative tells whether the curve is concave up or concave down at that point. If the second derivative is positive at a point, the graph is bending upwards at that point. Similarly, if the second derivative is negative, the graph is concave down. This is of particular interest at a critical point where the tangent line is flat and ...Recognizing the different ways that it can look for a function to paass through two points: linear, concave up, and concave down.Note that at stationary points of the expression, the curve is neither concave up nor concave down. In this case, 0 is a member of neither of the regions: In[5]:= Out[5]= To test that 0 is the only point where the second derivative is 0, use Resolve: In[6]:= Out[6]=Find step-by-step Biology solutions and your answer to the following textbook question: Determine where each function is increasing, decreasing, concave up, and concave down. With the help of a graphing calculator, sketch the graph of each function and label the intervals where it is increasing, decreasing, concave up, and concave down. Make sure that your graphs and your calculations agree ...

Example. Find the intervals on which is concave up and the intervals on which it is concave down. Find the x-coordinates of any inflection points. I set up a sign chart for , just as I use a sign chart for to tell where a function increases and where it decreases. The break points for my concavity sign chart will be the x-values where and the x-values where is undefined.We need to find the second derivative to determine concavity. f''(x) = -sinx - cosx Points of inflection occur when f''(x) = 0. cosx = -sinx This will occur at x = (3pi)/4 and (7pi)/4. We always need to check on both sides of the inflection point to make sure we go from positive to negative or negative to positive.Let's take a look at an example of that. Example 1 For the following function identify the intervals where the function is increasing and decreasing and the intervals where the function is concave up and concave down. Use this information to sketch the graph. h(x) = 3x5−5x3+3 h ( x) = 3 x 5 − 5 x 3 + 3. Show Solution.Find where graph is concave up and concave down and then find the point ofinflection of f(x)=ln(x2+1) This problem has been solved!

The graph is concave down when the second derivative is negative and concave up when the second derivative is positive. Concave up on (−∞,4) ( - ∞, 4) since f ''(x) f ′′ ( x) is …1. Suppose you pour water into a cylinder of such cross section, ConcaveUp trickles water down the trough and holds water in the tub. ConcaveDown trickles water away and spills out, water falling down. In the first case slope is <0 to start with, increases to 0 and next becomes > 0. In the second case slope is >0 at start, decreases to 0 and ...we can therefore determine that: (1) By solving the equation: f '(x) = 0 ⇒ −2xe−x2 = 0. we can see that f (x) has a single critical point for x = 0, this point is a relative maximum since f ''(0) = −2 < 0. Looking at the second derivative, we can see that 2e−x2 is always positive and non null, so that inflection points and concavity ...…
