a. (9, 4.5)

b. (9, -22.5)

c. (5, -6.5)

d. (5, 2.2)

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

i do not know the answer

step-by-step explanation:

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.
