Help(3x2 + 4x + 2) - (- x +4)
i need this and this in (-5x-6)-(4x2+6) standard form

3x2 + 4x − 4. A (x + 4) B(3x + 2) C(3x − 2) D(x − 2)    

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.
