The domain of a function is the set of input values the function can take

The radical function is not given; so, I will provide a general explanation

Assume the radical function is:

[tex]f(x) = \frac{1}{\sqrt{12- 2x}}[/tex]

The denominator of the above function cannot be negative.

So, we express the denominator as follows

[tex]12-2x > 0[/tex]

Subtract 12 from both sides

[tex]-2x > -12[/tex]

Divide both sides by -2

[tex]x < 6[/tex]

So, the possible values of x the function can take are less than 6

Hence, the domain of the radical function is [tex][-\infty,6][/tex]
