Please leave an explanation too !

-20=-20

Step-by-step explanation:

Distribute the 4.

(4xp-20)-8=4p-28

get rid of the variables (replace p with 2)

(8-20)-8=8-28

Simplify or combine like terms

-12-8=-20

Simplify or combine like terms

-20=-20

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.
