Whats the domain for the function 2x6 all over 7 just the si

What\'s the domain for the function 2x-6 all over 7? just the simple domain for this, not the codomain. I know I have to set the bottom equal to zero if it\'s a fraction when solving for the domain but I\'m confused as to what 7=0 is.

Solution

f(x) = (2x -6)/7

Here the denomnator is a constant 7 so it would never be zero (0).

Its a.linear fucntion and it has no restrictions on x values.

f(x) would exist all over real line number

So, Domain : ( - infinity , +infinity)
