Which function's domain consists of all real numbers except 3? a) f(x)=3x+3 b) f(x)=3/x-3 c) f(x)=3x^2 d) f(x)=3x-3 e) f(x)= 1/ square root of x-3,

b)

e)

Step-by-step explanation:

Since,  f(x) = 3x + 3, f(x) = 3x² and f(x) = 3x - 3 are polynomial function,

We know that,

The domain of a polynomial is the set of all real numbers,

⇒ Thus, the domain of the functions f(x) = 3x + 3, f(x) = 3x² and f(x) = 3x - 3 is the set of all real numbers,

Now, and are rational functions,

We know that,

The domain of a rational function is the set of all real numbers except those for which denominator = 0,

Hence, the domain of functions   and is the set of all real numbers except x = 3.
