Hey!! sooo confused? help:))

-4 I think

Step-by-step explanation:

Since it is about the origin and it is moving counterclockwise we first have to connect C to the origin. Once we do, we then make another line to form a right triangle but it has to be to the left since it is COUNTERclockwise, dont forget the many units from the origin to the original point c is about 4. So when we make the line to form the right triangle we have to reach 4 units, and 4 units up to the left is -4.

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.
