## Mean Value TheoremDrag the points a and b to create a closed interval. Click the check box to draw the secant line through the endpoints, and then draw a line that is parallel to the secant line. Find the point(s) on the graph of f(x) where the tangent line is parallel to the secant line. You can change the function by right-clicking on the graph, choosing "Function h," and then "Object Properties." BKD, Created with GeoGebra |
