Best ResponseYou've already chosen the best response.0@LollyLau yes looks like a horzontal line and it is definitely a function

Best ResponseYou've already chosen the best response.2F(x) = 2.5 It is not a function, because any function will have an 'x' with some coefficient. This is just a value. Also, the formula either for exponential or decay function isn't relevant to this one, so I don't think it is either a decay or an exponential function.

Best ResponseYou've already chosen the best response.2Adding to my previous post, F(x) = 2.5 is NOT a function because it's not in the form F(x) = 2.5x^2 or 2.5x or something. Ideally, a function is the one where you can select an input value and see the same for the output. For F(x) = 2.5 Whatever value x might have, the output is still 2.5 So, it's not a function, but rather, a constant value.

Best ResponseYou've already chosen the best response.0@ lollylau, yes, DC is a special case of a function, I know it because i studied all this in college. @Fall1213 f(x) is a function with a constant value for all x. @charlotteakina No hun, its not an exponential or decaying function. Exponetial function= a^x Exponetially decaying functions= a^ (x)

Best ResponseYou've already chosen the best response.2@piscez.in Thanks for the rectification. But in either case, it still neither an exponential or decay function.
