In the applet you see graphs of three functions. One of these is the "original" function, one is the first derivative, and one is the second derivative. Try to figure out which function is which color. Below the applet, click the color names beside each function to make your guess.

second derivatives give us about the shape of the graph of a function. The first derivative of the function f(x), which we write as f (x) or as df.

4. Up: Stat Previous: 2. 3. First and second derivative rules (2.2) First derivative rule If f'(a) > 0 then f(x) is increasing at x = a. If f'(a) < 0 then f(x) is decreasing at x = a. Second derivative rule If f''(a) > 0 then f(x) is concave up at x = a. If f''(a) < 0 then f(x) is concave down at x = a. If f''(a) = 0 then don't use this rule! Graphs for the key derivative cases.

30.03.2016 · Use concavity and inflection points to explain how the sign of the second derivative affects the shape of a function’s graph. Explain the concavity test for a function over an open interval. Explain the relationship between a function and its first and second derivatives. State the second derivative test for local extrema.

The Derivative Calculator supports computing first, second, …, fifth derivatives as well as differentiating functions with many variables (partial derivatives), implicit differentiation and calculating roots/zeros. You can also check your answers! Interactive graphs/plots help visualize and better understand the functions.

18.09.2017 · Video transcript. - [Instructor] We have the graphs of three functions here, and what we know is that one of them is the function f, another is the first derivative of f, and then the third is the second derivative of f. And our goal is to figure out which function is which. …

4.5.3 Use concavity and inflection points to explain how the sign of the second derivative affects the shape of a function’s graph. 4.5.4 Explain the concavity test for a function over an open interval. 4.5.5 Explain the relationship between a function and its first and second derivatives. 4.5.6 State the second derivative test for local extrema.

Therefore the second derivative test tells us that g(x) has a local maximum at x = 1 and a local minimum at x = 5. Inflection Points Finally, we want to discuss inflection points in the context of the second derivative. We recall that the graph of a function f(x) has an inflection point at x if the graph of the function goes from concave up ...

Looking at what the first and second derivatives tell us about the graph of a function. We use number lines ...

First derivative rule. If f'(a) > 0 then f(x) is increasing at x= a. If f'(a) < 0 then f(x) is decreasing at x= a. Second derivative rule. If f''(a) > 0 then f(x) is concave up at x= a. If f''(a) < 0 then f(x) is concave down at x= a. If f''(a) = 0 then don't use this rule! Graphs for the key derivative cases.

The following problems illustrate detailed graphing of functions of one variable using the first and second derivatives. Problems range in difficulty from average to challenging. If you are going to try these problems before looking at the solutions, you can avoid common mistakes by carefully labeling critical points, intercepts, and inflection points.

y = f ′ ( x ) . In other words, just as the first derivative measures the rate at which the original function changes, the second derivative measures the rate ...

The First and Second Derivative Tests The effect of f ′ on the graph of f Test for increasing / decreasing: a. If f ′(x) > 0 on an interval, then f is increasing on the interval. b. If f ′(x) < 0 on an interval, then f is decreasing on the interval. The First Derivative Test (for local maximum / minimum)
