Example Question #607 : Functions

Let  on the interval . Find a value for the number(s) that satisfies the mean value theorem for this function and interval.

Possible Answers:

Correct answer:

Explanation:

The mean value theorem states that for a planar arc passing through a starting and endpoint , there exists at a minimum one point, , within the interval  for which a line tangent to the curve at this point is parallel to the secant passing through the starting and end points.

Meanvaluetheorem

In other words, if one were to draw a straight line through these start and end points, one could find a point on the curve where the tangent would have the same slope as this line.

Note that the value of the derivative of a function at a point is the function's slope at that point; i.e. the slope of the tangent at said point.

First, find the two function values of  on the interval 

 

Then take the difference of the two and divide by the interval.

 

Now find the derivative of the function; this will be solved for the value(s) found above.

 

, which verifies the MVT, as it falls within
