Calculates the c point that satisfies the average value theorem for the next function in the interval [0. Calculate the point c that satisfies the average value theorem for the next function in the interval [0. Therefore, at point c, the equation of the slope of the ejercicioos line will be:.

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

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:. What the theorem of the average value says is that if all the previous conditions are fulfilled, which we have seen yes, then ro,le 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:.

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

The average value theorem says that ejercivios is at least one point c, which verifies all teoorema the above, or in other words, that there can be more than one point.

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:. 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:. This theorem is explained in the 2nd year of high school when the applications of the deviradas are studied.

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

In this case, as we see in the graph of the function, we have another point d where the line tangent to the function is parallel to the line passing through A and B:. For the function to be derivable, its derivative must be continuous.

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:. It is continuous in [0,1] and derivable in 0,1therefore, there is a value of c in that interval such that:.

## An error occurred.

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

Therefore, we obtain the derivative of the function:. First of all, we must check if the conditions are fulfilled so that the theorem of the average value can be applied.

We have to check that the function is continuous and devirable in that interval. Let us now see some examples of how to apply the average value theorem and calculate the c point of the theorem.

The equation of the slope of the tangent line at a point is equal to that ejeecicios from the function at that point. 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:. We must check if the equation is continuous in [0,1] and ekercicios in 0,1.
