To qualify for Gold status at Awesome Airlines, one must fly at least 9600 and less than 38400 miles each year. If Greg takes a 800-mile round-trip flight to visit his parents, how many times does Greg need to visit his parents each year to attain Gold status? Express your answer in interval notation​

ou would have 12 of each

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.
