$\text{ }$
Domain of the function

color(red)(f(x) = 2(x-3)^2+1 is given by

color(blue)((-oo < x < oo)

In interval notation: color(blue)((-oo,oo)

#### Explanation:

$\text{ }$
Given:

color(red)(f(x) = 2(x-3)^2+1

Domain is the set of all input values that generate the output values for the function.

For the values, the function is defined.

There are no values that makes the function undefined.

Hence,

Solution:

color(blue)((-oo < x < oo)

In interval notation:

color(blue)((-oo,oo)
