Some body knows how to form a subset?

Subset is part of set which is obtained from Universal set.

Step-by-step explanation:

Like for example :-

A - ( 1,2,3,4,5,6,7,8)

And B - ( 1,2 , 3)

So we can say B is subset of A.

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.
