If Anna and Tamera drive 5x - 5 hours over the four days and the plan to travel 4.5 hours each day (x = 4.5), how many hours will they drive over the four days? Note
the expression 5x - 5 represents the total time traveled.

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
