You're a copywriter working on a billboard for a local government agency. The project includes a rectangular fact sheet that you need to scale up to fill part of the
billboard. If the original graphic is 1 foot wide and 2 feet tall, and you need it to be
5 feet wide for the billboard, how tall should the graphic be?
10 feet
20 feet
15 feet

1 number

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.

answer: i dont know but if you try hard you will get it right : )
