Step-by-step explanation:
f(x)=x

in interval [2,4].
Now, checking the conditions for mean value theorem
Since, f(x) is a polynomial, it is continuous in (2,4).
Also, it is differentiable in (2,4).
Now, a=2 and b=4
f(a)=f(2)=4
f(b)=f(4)=16
f(x)=x

f

(x)=2x
f
′
(c)=2c
Now,
f
′
(c)=
b−a
f(b)−f(a)
2c=
4−2
16−4
2c=6
c=3
c=3∈(2,4)
Hence, Mean value theorem is satisfied.
