Chapter 2.5, Problem 77E
To determine

## To state : whether the function f(x)=x2+x is even, odd or neither.

Expert Solution

The function f(x)=x2+x is neither.

### Explanation of Solution

Given information :

The function is f(x)=x2+x

The function f is even if f(x)=f(x) for all x in the domain of f .

The function f is odd if f(x)=f(x) for all x in the domain of f .

f(x)=x2+xf(x)=(x)2+(x)f(x)=x2xf(x)f(x) and f(x)f(x)

since, f(x)f(x) and f(x)f(x) we conclude that f(x)=x2+x neither even nor odd fnction.
