Chapter 2.7, Problem 21E

To determine

**To find:**The derivative of the given function by definition of derivative and state the domain of the function and the domain of its derivative.

Expert Solution

Derivative of the function is

Domain of the function and domain of derivative is set of real number.

**Given: **

**Concept used: **

Definition of derivative:

It has to find derivative of the function.

Domain of the function is the set of all possible input of the function, so here domain of the function is set of real numbers.

Domain of the derivative is the set of all points in the domain of function at which function is differentiable.

Hence, domain of derivative and domain of function both are set of real number.
