What does the closed dot on the number line

It turns out that all real numbers from 2 through 2 make the inequality true. When you graph on the number line, a closed dot indicates that the number is part of the graph. The = symbol indicates that the number being compared is included in the graph.

it is also equal to that number

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.
