Solution

The correct option is A

-3


Explanation for the correct option:

Finding the value of the expression:

Given that,

fx=x-2+x+1-x

Differentiate the given function with respect to x.

f'x=x-2x-2+x+1x+1-1[dxdx=xxorxx]

Now, substitute x=-10 in the derivative,

f'-10=-10-2-10-2+-10+1-10+1-1=12-12+9-9-1=-3

Hence, the correct option is A.
