Application +4 | -1

The value of

c

in the Lagrange’s mean value theorem for the function

f(x) = \,{x^3} - 4{x^2} + 8x + 11,

when

x \in \,[0,\,1]

View answer and explanation

Correct option: D

\frac{{4 - \sqrt 7 }}{3}

Option D (

\frac{{4 - \sqrt 7 }}{3}

) is correct because it is the value of

c

obtained by applying Lagrange's Mean Value Theorem to the given function on the specified interval.
