Is 24 x 10^-9 written in proper scientific notation?

Yes. In scientific notation the exponent and the power of 10 represent/indicate how many zeros are in it's place.

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: -0.5 would be the most likley outcome
