Question
gail is thinking of a number n, and she wants her sister to guess the number. her first clue is that nine less than two times
her number is between negative seven and one. write a compound inequality that shows the range of numbers that gail
might be thinking of.

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: 323 is how many she has ☃☃⛄❄
