I need help! Jeff sold half of his comic book collection. Two years later he decides to start collecting again. After buying 12 comics, he now has a total of 35. Write and solve an equation for x as the number of comics Jeff had before he sold half of them.

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.
