The equation of the slope of the tangent line at a point is equal to that derived from the function at that point. For the function to be derivable, its derivative must be continuous. Find a and b for f x to meet the conditions of the average value theorem in [0,2] and calculate the c point that satisfies the average value theorem for that interval:.

Therefore, this function fulfills the conditions for the theorem of the average value to be fulfilled.

The first section depends on c, so we equal it to the value of f’ c that we have obtained before and we clear the value of c:. In this case, as we see in the graph of georema function, we have another point d where the line deo to the function is parallel to the line passing through A and B:. Calculates the c point that satisfies the average value theorem for the next function in the interval [0.

We must check if the equation is continuous in [0,1] and derivable in 0,1. When two lines are parallel, it means that they have the same slope, so the slope of the tangent line at point c and the slope of the line through A and B are equal and therefore:. Therefore, at point c, the equation of the slope of the tangent line will be:.

They fulfill the two obligatory conditions, then the theorem of the average value can be applied and there will be a point c in the interval [0,4] such that:. Calculate the point c that satisfies the average value theorem for the next function in the interval [0. It is continuous in [0,1] and derivable in 0,1therefore, there is a value of c in that interval ejerciccios that:.

We already know that the function is continuous and derivable, so we now calculate the value of the function at the extremes of the interval:. What the theorem of the average value says is that if all the previous conditions are fulfilled, which we have seen yes, then there is at least one point c, in which the tangent line at that point is parallel to the line that passes through points A and B:.

The function is continuous in all R, being a polynomial function, so it will also be continuous in the interval [0,1].

## Average or Lagrange value theorem. Exercises solved step by step.

Let us now see some examples of how to apply the average value theorem and calculate the c point of the theorem. In the first stretch we get no value of c, but in the second stretch, it depends on c, which we equal to the value of f’ c previously calculated and we get what c is worth:.

Therefore, we obtain the derivative of the function:. This theorem is explained in the 2nd year of high school when the applications of the deviradas are studied.

## An error occurred.

First of all, we must check if the conditions are fulfilled so that the theorem of the average value can be applied. The average value theorem says that there is at least one point c, which verifies all of the above, or in other words, that there can be more than one point. We have to check that the function is continuous and devirable in that interval.

We match both results of f’ c and we are left with an equation that depends on c and where we can clear it and find the value of c they are asking for:.
