Scientists measure a bacteria population and find that it is 10,000. Five days later, they find that the population has doubled. Which function could describe the bacteria population days after the scientists first measured it, assuming it grows exponentially? a. () = 10, 000 ⋅ 2 b. () = 10, 000 ⋅ (√2 5 ) c. () = 10, 000 ⋅ ( 1 √2 5 ) d. () = 10, 000 ⋅ 2 5

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.
