Question

For which value of x is the function 2x^2 + 3x + 1/x - 1 g(x) undefined? ​

Answer 1

See below

Explanation:

We have

`g(x)=2x^2 + 3x + (2)/(x) - 1`

The function is true
`\forall x \in\mathbb{R}` except 0, because division by zero is undefined.

Therefore, the domain of the function can be written as

`Dom(g) = \mathbb{R}-\{0\} \text{ or } (-\infty, 0)\cup (0, \infty)`
