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.

false

step-by-step explanation:

false : it can not go to 9 the highest that part can go is 7

here is your proof

the answer is d

for problems like this theres an app, its photomath that explains the problem and gives the answer hope i
