Chapter 2, Problem 52RE
To determine

## Use a graphical device; find the domain of the function f(x)=x4−x3+x2+3x−6

Expert Solution

The domain of the function f(x)=x4x3+x2+3x6 is (,)

### Explanation of Solution

Given information: consider the function f(x)=x4x3+x2+3x6

Calculation:

Use a graphical device; we sketch the graph of the function f(x)=x4x3+x2+3x6 as shown below:

From the above figure, we observe that the domain is (,)

Thus, the domain of the function f(x)=x4x3+x2+3x6 is (,)
