Best ResponseYou've already chosen the best response.0Equaltion = An equality containing one or more variables. In other words, anything that has an "x" (the letter isn't important) and an equal in it. (2x=5, x^26=0, even x+y=3). Function = a relationship between a set of inputs and a set of outputs. f(x) = 2 for x belonging to real numbers That means that regardless of what x you put in, the function will always be 2. f(x) = x for x belonging to real numbers That means that regardless of what x you put in, the function will always be x. f(x) = x3 for x belonging to (3,5) That means that if the x that you put in has values between 3 and 5, the function will always be x3. It also means that for any other values outside (3,5) your function cannot return an answer to you, because the function is undefined in that domain. Think of functions as laws  either they're universal (when x belongs to real numbers and you can put it any number in) or local (when the law only applies for certain people, certain values of x  and outside of it, it doesn't).

Best ResponseYou've already chosen the best response.0And yes, f(x) = 4x  5 would be one because: a) it's an equation, it represents an equality describing at least one variable (in this case, x) b) it's a function, it represents the relationship between an input (x) and an output ( f(x) )
