Question

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

Answer 1

Answer:

See below

Step-by-step explanation:

We have

$g(x)=2x^2 + 3x + \dfrac{2}{x} - 1$

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

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