.

the function of f(x) = x + sin (x) on the interval [0,b]

i have to find b.

two values of c that are given are (4.6658, 1.6174) that satisfy the mean value theorem on [0,b]

i got b as +/- 3.29 but it has to be an integer so i think that's wrong.

'

can someone please help me with this problem?
