How to Locate Intervals of Concavity and Inflection Points

1. Find the second derivative of f.
2. Set the second derivative equal to zero and solve.
3. Determine whether the second derivative is undefined for any x-values.
4. Plot these numbers on a number line and test the regions with the second derivative.

Where is concave up and down in Symbolab?

An inflection point is a point on the graph at which the second derivative is equal to zero or undefined and changes sign . If f ′′( x )>0 then f ( x ) concave upwards . If f ′′( x )<0 then f ( x ) concave downwards .

How do you find the intervals of concave up and down?

To find which interval is concave down, find the second derivative of the function. Now, find which values in the interval specified make . In this case, and . and plug in those values into to see which will give a negative answer, meaning concave down, or a positive answer, meaning concave up.

How do you find the intervals of concave up and down on a graph?

Exercise

1. The graph of y = f (x) is concave upward on those intervals where y = f “(x) > 0.
2. The graph of y = f (x) is concave downward on those intervals where y = f “(x) < 0.
3. If the graph of y = f (x) has a point of inflection then y = f “(x) = 0.

How do you find the intervals of increase and decrease?

Explanation: To find increasing and decreasing intervals, we need to find where our first derivative is greater than or less than zero. If our first derivative is positive, our original function is increasing and if g'(x) is negative, g(x) is decreasing.

How do you find inflection points on a graph?

An inflection point is a point on the graph of a function at which the concavity changes. Points of inflection can occur where the second derivative is zero. In other words, solve f ” = 0 to find the potential inflection points. Even if f ”(c) = 0, you can’t conclude that there is an inflection at x = c.
