Our domain would be #(0, infty)#.īe on the lookout for what values of #x# "break" a function and you will be better able to see where domain restrictions should exist. Possible Cause: EAC requires the OWA authentication module from the same web site, this may contribute to the MFA issue. This co-dependency between OWA and ECP is also affecting RSA mfa which I have enabled on OWA only but is also affecting ECP. With the function #f(x) = 2log_4(x) - 3#, we recall that you cannot take the logarithm of zero or a negative number. Tried to block ECP access to a subnet in the local network with IIS ip and domain restrictions. Thus, our domain for this function only includes values greater than or equal to 2. Thus, we must have #2x-4# be non-negative. With the function #f(x) = -sqrt(2x-4) + 7#, we recall that you cannot take the square root of a negative number. Thus, this function has a domain of #(-infty, infty)#. You can raise a constant to any number, positive, negative or zero, and it will still be defined. To discover the domain, ask yourself, "Is there any value of #x# I can plug in that breaks some math rule"? In this case, there is not. These both will give you some insight as to what values, if any, need to be excluded from the domain. When trying to find the domain of a function, it helps to plug in some values in your head as well as consider the parent graph. The domain, then, would consist of all values except zero. Here, you can plug in every value except #x = 0#, precisely because #1/0# is not defined. Informally, the domain for some function #f(x)# consists of all the values of #x# you are allowed to plug in without "breaking" the rules of math.įor example, consider the function #f(x) = 1/x#.
