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

The answer is e. To determine the domain you must first find all possible x-values that allow a function to work resulting in real y-values. The bottom number of a fraction can never be 0. In all other options 3 is one of the real numbers.
