ANSWER

The two functions have the same range.

EXPLANATION

The given function is

[tex]g(x) = \frac{6}{x} [/tex]

Let:

[tex]y = \frac{6}{x} [/tex]

We solve this equation for x,

[tex]x = \frac{6}{y} [/tex]

x is defined for:

[tex]y \ne0[/tex]

Hence the range is

[tex]y \ne0[/tex]

Also,

[tex]f(x) = \frac{1}{x} [/tex]

Let

[tex]y = \frac{1}{x} [/tex]

[tex]x = \frac{1}{y} [/tex]

The range for this function is also,

[tex]y \ne0[/tex]

Hence the two functions have the same range
